7.1 English Sentence Structure, Run-ons, Comma Splices & Fragments

7.1 English Sentence Structure, Run-ons, Comma Splices & Fragments

Quick Answer: The FCICE Written Error Detection subtest evaluates candidates' mastery of formal legal syntax and punctuation mechanics. Success requires rapid identification of core structural flaws: comma splices (joining two independent clauses with only a bare comma), fused sentences (running independent clauses together without punctuation or conjunctions), sentence fragments (subordinate clauses or participial phrases masquerading as complete sentences), defective coordination (using conjunctive adverbs like however as coordinating conjunctions), misplaced relative pronouns (that vs. which), and failure to invert after negative or restrictive adverbials (under no circumstances, seldom).

In the federal judicial system, grammatical precision is inseparable from legal validity. A misplaced comma in a statutory exception, a dangling participle in a Title III wiretap affidavit, or an ambiguous relative clause in a plea agreement can alter the legal rights of criminal defendants, trigger evidentiary suppression, or produce conflicting circuit interpretations. For the federally certified court interpreter, detecting structural and grammatical defects is both an explicit testing component of the Written Phase — Part III, Error Detection, in each language section — and an indispensable skill for rapid sight translation and accurate simultaneous interpretation.

1. Anatomy of the FCICE Written Error Detection Task Type

Administered on computer terminals through Prometric, the English Language portion of the FCICE Written Examination devotes substantial weight to Error Detection and Sentence Structure. Questions present elevated legal, administrative, and constitutional English text drawn from authentic courtroom transcripts, appellate opinions, federal statutory compilations (Titles 18, 21, 28 U.S.C.), and procedural rules (Fed. R. Crim. P., Fed. R. Civ. P., Fed. R. Evid.).

Candidates encounter two primary presentation formats:

Format A: The Four-Segment Underlined Sentence

A single complex legal sentence contains four underlined words or phrases labeled (A), (B), (C), and (D). The candidate must identify the single segment containing a grammatical, structural, or lexical defect, or select (E) / "No error" if the sentence is completely standard.

[Sample Format A]:
Notwithstanding the magistrate judge's explicit warning, the defendant refused to surrender
                  (A)                                                 (B)
his passport, moreover, he attempted to transfer liquid assets to an offshore account. No error.
                (C)                                       (D)                   (E)

Analysis: Segment (C) is defective. The transitional word moreover is a conjunctive adverb, not a coordinating conjunction. Linking two independent clauses with a bare comma before moreover produces an ungrammatical comma splice. The sentence requires a semicolon preceding moreover (...passport; moreover, he attempted...).

Format B: The Four-Sentence Discrimination Set

Four distinct sentences are presented, each addressing a legal or administrative topic. Candidates must identify the single sentence that is grammatically defective or, conversely, the single sentence that is completely free of error.

The Cognitive Challenge for Bilingual Interpreters

Spanish syntax is inherently more syntactically flexible and tolerant of clause juxtaposition (asíndeton) than formal English. In Spanish formal writing, joining two related complete thoughts with a comma followed by an adverbial connector ("El acusado guardó silencio, sin embargo, su cómplice confesó") is standard stylistic practice. In formal English, that identical structure ("The defendant remained silent, however, his accomplice confessed") is an ungrammatical comma splice. Interpreters whose syntactic intuitions are calibrated primarily to Spanish frequently overlook comma splices, run-on sentences, and missing auxiliary inversions.

2. Core Structural Defects: Comma Splices, Fused Sentences & Disguised Fragments

An independent clause contains a subject and a finite predicate verb and expresses a complete, standalone thought. In English syntax, two independent clauses cannot simply collide without an authorized structural bridge.

INDEPENDENT CLAUSE [A]                           INDEPENDENT CLAUSE [B]
"The grand jury returned a true bill"           "The defendant was remanded to custody"
──────────────────────────────────────           ───────────────────────────────────────
  FAULTY JUNCTION 1 (Comma Splice):             [A] , [B]                 [DEFECTIVE]
  FAULTY JUNCTION 2 (Fused / Run-on):           [A] [B]                   [DEFECTIVE]
  FAULTY JUNCTION 3 (Conjunctive Adverb Splice):[A] , however, [B]        [DEFECTIVE]
  LEGAL JUNCTION 1 (Semicolon):                 [A] ; [B]                 [VALID]
  LEGAL JUNCTION 2 (Comma + FANBOYS):           [A] , and [B]             [VALID]
  LEGAL JUNCTION 3 (Semicolon + Conj. Adverb):  [A] ; however, [B]        [VALID]
  LEGAL JUNCTION 4 (Period / Separate):         [A] . [B]                 [VALID]

A. Comma Splices (Coma Criminal / Yuxtaposición Defectuosa)

A comma splice occurs when two independent clauses are joined by only a bare comma without an intervening coordinating conjunction. In legal prose, comma splices most frequently occur when the clauses are short or closely related in topic:

• Defective: "The court heard oral argument on the motion to suppress, it reserved judgment until Friday."
• Corrected (Semicolon): "The court heard oral argument on the motion to suppress; it reserved judgment until Friday."
• Corrected (Coordinating Conjunction): "The court heard oral argument on the motion to suppress, but it reserved judgment until Friday."
• Corrected (Subordination): "After hearing oral argument on the motion to suppress, the court reserved judgment until Friday."

B. Fused (Run-on) Sentences (Oraciones Fisionadas / Continuadas)

A fused sentence occurs when two independent clauses are juxtaposed with no punctuation or conjunction whatsoever. In legal drafting, this defect often arises when complex parenthetical phrases obscure where one clause ends and the next begins:

• Defective: "The special agent executed the search warrant under Rule 41 he recovered seven kilograms of fentanyl hidden in the ventilation ducts."
• Corrected: "The special agent executed the search warrant under Rule 41; he recovered seven kilograms of fentanyl hidden in the ventilation ducts."

C. Disguised Sentence Fragments (Fragmentos Oracionales Encubiertos)

A sentence fragment is a dependent clause, participial phrase, or prepositional phrase standing alone with a capital letter and a period, devoid of an independent finite clause. On the FCICE, fragments are never obvious two-word phrases; they are dense, high-register syntactic units that exceed 25–40 words, often disguised by introductory participial phrases, nested relative clauses, and technical legal lexis:

• Defective (Subordinate Clause Fragment): "Although the defense counsel vigorously cross-examined the forensic toxicologist regarding the calibration logs of the gas chromatograph, and demonstrated that the maintenance records had been forged by the lab technician."
  • Analysis: This 32-word construction contains an introductory subordinating conjunction (Although), followed by a compound predicate (cross-examined... and demonstrated), but no independent main clause ever appears. The entire thought remains syntactically suspended.
  • Corrected: "Although the defense counsel vigorously cross-examined the forensic toxicologist regarding the calibration logs of the gas chromatograph and demonstrated that the maintenance records had been forged by the lab technician, the district judge denied the motion to exclude the forensic report."
• Defective (Participial Phrase Fragment): "Having established that the wiretap authorization expired at midnight on October 14, and that all subsequent interceptions conducted by the task force constituted warrantless electronic surveillance in violation of Title III."
  • Analysis: The entire unit consists of a participial phrase headed by Having established, governing two subordinate noun clauses (that... and that...). There is no finite subject or main verb.
  • Corrected: "Having established that the wiretap authorization expired at midnight on October 14 and that all subsequent interceptions constituted warrantless electronic surveillance, the defense moved to suppress the recorded conversations."

3. Coordination vs. Subordination in Legal Prose

One of the most heavily tested syntactic distinctions on the FCICE Written Phase is the boundary separating coordinating conjunctions from conjunctive adverbs.

The Seven Coordinating Conjunctions (FANBOYS)

English possesses exactly seven coordinating conjunctions, easily recalled by the mnemonic FANBOYS:

1. For (causal / explanatory)
2. And (additive)
3. Nor (negative disjunctive)
4. But (adversative)
5. Or (alternative)
6. Yet (concessive adversative)
7. So (consequential)

When any of these seven conjunctions joins two independent clauses, a comma must precede the conjunction:

• "The defendant declined to enter a guilty plea, for he maintained that the confession was coerced."
• "The prosecutor proffered the surveillance logs, but the trial judge excluded them under Rule 403."
• "The witness did not sign the cooperation agreement, nor did she appear before the grand jury."

Conjunctive Adverbs (Transitional Connectors)

Conjunctive adverbs express logical relationships (contrast, consequence, addition) but lack the grammatical capacity to join clauses. Common legal conjunctive adverbs include:

• however, moreover, nevertheless, furthermore, consequently, therefore, accordingly, nonetheless, thus, indeed, meanwhile, instead, subsequently.

When a conjunctive adverb appears between two independent clauses, it must be preceded by a semicolon (or period) and followed by a comma:

INCORRECT:  The motion was untimely, however, the court considered it in the interest of justice.
CORRECT:    The motion was untimely; however, the court considered it in the interest of justice.
CORRECT:    The motion was untimely. However, the court considered it in the interest of justice.

Exam Trap Alert: Test writers frequently create questions where however appears with a bare comma, betting that candidates will read it phonetically and overlook the comma splice. If the word following the comma can be replaced by but, check whether it is a conjunctive adverb (however) masquerading as a coordinating conjunction!

Semicolons with Internal Commas

A secondary rule heavily tested in complex legal prose: when independent clauses already contain extensive internal commas (such as series, parenthetical appositives, or non-restrictive clauses), a semicolon is required before a coordinating conjunction to prevent visual and syntactic confusion:

• "The government called Special Agent Miller, who oversaw the electronic wiretap; Lieutenant Vance, the tactical commander; and Dr. Aris, the forensic toxicologist; but despite this formidable witness list, the jury acquitted the defendant on all conspiracy counts."

4. Restrictive vs. Non-Restrictive Relative Clauses: That vs. Which

In formal federal legal drafting—guided by canonical authorities such as Bryan Garner (Garner's Modern English Usage) and Justice Antonin Scalia—the distinction between restrictive and non-restrictive relative clauses is rigid and substantive.

A. Restrictive (Essential) Clauses: That

A restrictive clause provides information essential to identifying the precise noun it modifies. Without it, the sentence's substantive legal meaning is destroyed or fundamentally altered. Restrictive clauses:

• Must be introduced by that (or who/whom for human antecedents).
• Are never set off by commas.
• Limit the class of items under discussion.

Example: "Warrantless searches that fall outside established exceptions are per se unreasonable under the Fourth Amendment."

• Meaning: Only the subset of warrantless searches lacking an exception is unreasonable. Searches with valid exceptions (e.g., exigent circumstances, plain view) remain constitutional.

B. Non-Restrictive (Non-Essential) Clauses: Which

A non-restrictive clause provides supplemental, parenthetical information about a noun that is already fully defined and identified. If the clause were excised, the core legal proposition would remain intact. Non-restrictive clauses:

• Must be introduced by which (or who/whom for human antecedents).
• Must be bracketed by paired commas (or a comma and a period).
• Apply to the entire class of the antecedent.

Example: "The search warrant, which was executed at midnight, failed to describe the premises with particularity."

• Meaning: There was only one search warrant. It failed to describe the premises with particularity. The fact that it was executed at midnight is merely supplemental factual color.

The Legal and Constitutional Stakes

Observe how an errant comma in a judicial decree reverses legal reality:

• Sentence 1 (Restrictive): "The seized narcotics that were tested by the discredited laboratory technician must be suppressed."
  • Legal Effect: Only the specific narcotics handled by that rogue technician are suppressed; the remaining narcotics remain admissible.
• Sentence 2 (Non-Restrictive): "The seized narcotics, which were tested by the discredited laboratory technician, must be suppressed."
  • Legal Effect: All the seized narcotics are suppressed, because the non-restrictive clause implies that the entire universe of seized narcotics was tested by the rogue technician.

5. Subject-Auxiliary Inversion after Negative & Restrictive Adverbials

In formal, literary, and elevated judicial English, when a negative, restrictive, or limiting adverbial phrase is placed at the head of a clause (for rhetorical emphasis or solemnity), canonical English word order (Subject + Auxiliary Verb) must be inverted to Auxiliary Verb + Subject.

CANONICAL DECLARATIVE:       The court had seldom witnessed such prosecutorial overreach.
FRONTED NEGATIVE ADVERBIAL:  SELDOM had the court witnessed such prosecutorial overreach.
                             ────── ─── ───────── ─────────
                             Adverb Aux  Subject    Main Verb

Mandatory Inversion Triggers in Courtroom Prose

The following introductory negative and restrictive adverbial constructions trigger mandatory subject-auxiliary inversion:

1. Under no circumstances (Bajo ninguna circunstancia): "Under no circumstances may a prosecutor comment on a defendant's post-arrest silence." (Not: "Under no circumstances a prosecutor may comment...")
2. Seldom / Rarely (Rara vez / En contadas ocasiones): "Seldom has a federal court granted a writ of mandamus against an administrative agency."
3. Barely / Scarcely / Hardly ... when (Apenas ... cuando): "Barely had the cooperating witness begun his direct examination when defense counsel objected."
4. At no time / In no way (En ningún momento / De ninguna manera): "At no time did the DEA agents advise the suspect of his Miranda rights during the custodial transit."
5. Not only ... but also (No solo ... sino también): "Not only did the defendant falsify the corporate balance sheets, but he also forged the independent auditor's signature."
6. In no event (En ningún caso): "In no event shall the magistrate judge extend the detention period without conducting a formal evidentiary hearing."
7. No sooner ... than (Apenas ... cuando / Tan pronto como): "No sooner had the jury retired to deliberate than the alternate juror disclosed an impermissible external communication."
8. Only after / Only when (Solo después de / Solo cuando): "Only after reviewing the unredacted surveillance logs did the trial judge realize that the search warrant lacked probable cause."

Exam Trap Alert: When an item on the FCICE Written Exam opens with Under no circumstances, At no time, Seldom, or Not only, immediately scan the following clause for an auxiliary verb (did, had, was, is, may, can). If the subject appears before the verb (e.g., "Under no circumstances the government may..."), it is an unequivocal structural error.
