5.3 Form, Structure & Sense: Verb Finiteness
Key Takeaways
- College Board's testing point: use verbs and verbals — gerunds, participles, and infinitives — in contextually appropriate ways.
- The decisive question is whether the clause already has a main verb: if it does not, the blank needs a finite verb; if it does, the blank needs a verbal.
- A clause whose only verb-shaped word is an -ing, -ed, or to + verb form is a fragment, so finiteness items and Boundaries items often overlap.
- Irregular past participles (written, taken, begun, seen) differ from simple past forms (wrote, took, began, saw), and reduced relative clauses require the participle.
- Items in a series must share the same verb form; a series mixing a gerund, an infinitive, and a finite verb is never correct.
The Testing Point
Students will use verbs and verbals (i.e., gerunds, participles, infinitives) in contextually appropriate ways. That is College Board's definition, and the word doing the work is verbals.
A finite verb carries tense and can be the main verb of a clause: walks, walked, will walk, has walked. A verbal is verb-derived but cannot be a main verb:
| Verbal | Form | Function | Example |
|---|---|---|---|
| Gerund | -ing | noun | "Studying improved her scores." |
| Present participle | -ing | adjective | "The team, struggling with funding, paused the trial." |
| Past participle | -ed / irregular | adjective, or pairs with have/be | "The data, collected in June, supported the claim." |
| Infinitive | to + verb | noun, adjective, or adverb | "She decided to publish." |
The One Question That Decides Everything
Does the clause already have a main verb?
- No main verb yet → the blank needs a finite verb, or the clause is a fragment.
- Main verb already present → the blank needs a verbal, or you get two competing main verbs.
The manuscript ______ by three authors over four years, was finally published in June.
The clause already has "was published." So the blank cannot hold another finite verb; it needs a participle: written. Choosing "was written" would produce "The manuscript was written by three authors…, was finally published," which has two main verbs and no join.
The manuscript, written by three authors over four years, ______ finally published in June.
Here the participial phrase is already set off, and the clause has no main verb yet. Now the blank needs a finite verb: was.
Same words, opposite answers, decided entirely by what else is in the clause.
Reduced Relative Clauses
A very common item shape hides a relative clause:
The report ______ by the external auditor last week is now public.
Expand it mentally: the report that was revised by the external auditor last week. When that was is dropped — a reduced relative clause — what remains must be a past participle: revised.
- ✗ revising — a present participle, which would mean the report did the revising
- ✗ to revise — an infinitive, which cannot modify a noun this way
- ✗ revision — a noun, not a verb form at all
The direction of the action is the giveaway: if the noun receives the action, use the past participle; if it performs the action, use the present participle.
- "The auditor, reviewing the ledger, found the error." (auditor performs)
- "The ledger, reviewed by the auditor, showed the error." (ledger receives)
Irregular Past Participles
For irregular verbs, the past participle differs from the simple past, and the exam exploits it.
| Verb | Simple past | Past participle |
|---|---|---|
| write | wrote | written |
| take | took | taken |
| see | saw | seen |
| begin | began | begun |
| go | went | gone |
| drink | drank | drunk |
| choose | chose | chosen |
| break | broke | broken |
The past participle is what follows have/has/had and what modifies a noun. "The manuscript, written by three authors" — never "wrote by three authors." "She had begun" — never "she had began."
Verb + Complement Idiom
Some verbs take an infinitive complement, others a gerund. This is idiom, not logic, so it has to be learned.
| Takes an infinitive (to + verb) | Takes a gerund (-ing) |
|---|---|
| decide, hope, plan, refuse, agree, offer, promise, manage, fail, attempt | enjoy, finish, avoid, consider, suggest, deny, risk, practice, resist, postpone |
- ✓ "The committee decided to publish the findings."
- ✓ "The committee finished reviewing the findings."
- ✗ "The committee decided publishing…" / "The committee finished to review…"
Some verbs (begin, continue, like, prefer) accept either with no change in meaning, so the exam avoids them.
Parallel Verb Forms in a Series
Items in a series must share one form. This is where finiteness meets parallelism, and it is a recurring item shape.
| Not parallel | Parallel |
|---|---|
| "The protocol requires designing the study, collecting data, and to analyze the results." | "…designing the study, collecting data, and analyzing the results." (all gerunds) |
| "She likes hiking, swimming, and to run." | "She likes hiking, swimming, and running." |
| "The plan will survey the site, map the drainage, and recommending repairs." | "…survey the site, map the drainage, and recommend repairs." (all bare infinitives sharing will) |
Watch what the series shares. In "requires researchers to design the study, collect data, and ______," the single to governs all three items, so the third must be a bare verb — analyze, not to analyze and not analyzing.
Worked Examples
Example 1. "The dataset ______ from four monitoring stations between 2019 and 2023 has not yet been released." The clause has "has been released." Reduced relative clause, dataset receives the action → compiled.
Example 2. "Having reviewed the transcripts, the committee ______ to release a summary." The opening participial phrase is not the main verb; the clause still needs one → voted (finite), and vote takes an infinitive complement, which the sentence already supplies.
Example 3. "The grant supports acquiring the instruments, training the technicians, and ______ the results." The series is gerunds → publishing.
Section Takeaways
- Ask whether the clause already has a main verb; that single fact decides finite versus verbal.
- Reduced relative clauses ("the report [that was] revised") require a past participle.
- Irregular past participles differ from simple past forms; only the participle follows have/had or modifies a noun.
- Decide/hope/refuse take infinitives; enjoy/finish/avoid take gerunds.
- Every item in a series must share one verb form, including whether a shared to is repeated.
