2.2 Homophones and Commonly Confused Words

Key Takeaways

  • Homophones are correctly spelled words used in the wrong slot—TEAS error-identification items often hinge on meaning, not letter patterns alone.
  • Master contraction vs possessive pairs: they're/their/there, you're/your, it's/its, who's/whose—apostrophe forms stand for missing letters (they are, you are, it is/has, who is/has).
  • Affect is usually a verb (to influence); effect is usually a noun (a result). Accept means receive; except means exclude.
  • Principal is a person or main amount; principle is a rule. Stationary means not moving; stationery means paper supplies.
  • Use memory hooks (then = time sequence; than = comparison; lose = opposite of win; loose = not tight) and reread the full sentence before choosing.

Homophones on TEAS: the real trap is meaning

A homophone is a word that sounds like another word but has a different spelling and meaning (their / there / they're). Closely related are commonly confused words that may not sound identical in every dialect but are still mixed up in writing (affect / effect, loose / lose).

On TEAS 7 English and Language Usage, these items usually look like:

  • “Which sentence is correct?”
  • “Which word best completes the sentence?”
  • “Which underlined word should be changed?”

Unlike pure spelling-rule items in Section 2.1, every option may be a real English word. Your job is to match grammar role + meaning to the sentence. Healthcare and school contexts are common because they produce natural sentences with patient, effect, principal, advice, and your.

TEAS-style error-identification framing

  1. Read the whole sentence, not just the blank.
  2. Expand any possible contraction (it's = it is / it has).
  3. Ask what part of speech the slot needs (noun? verb? possessive?).
  4. Eliminate options that are spelled like the right sound but fail the meaning test.

Core contraction vs possessive pairs

twonumber 2countingTwo tablets were administered.

Memory hooks that stick under timed conditions

  • They're / you're / it's / who's all contain a verb hiding inside the apostrophe. If “they are / you are / it is / who is” sounds wrong in the sentence, reject the contraction.
  • Its is possessive like his or hers—those words have no apostrophe, and neither does its.
  • There has here inside it if you rearrange letters—both relate to place.
  • Their has heir (ownership inheritance) as a loose mnemonic for possession.
  • Two is the only form that is clearly a number.

Healthcare sentence drills

  • Correct: “The patient left their belongings there, and they're asking for a nurse.”
  • Correct:You're responsible for checking your ID badge.”
  • Correct:It's clear that the pump lost its battery charge.”
  • Correct:Who's the nurse whose patient needs a dressing change?”
  • Correct: “Send the specimen to the lab; the wait was too long for two draws.”

Common TEAS trap

Writers who are strong spellers still miss its/it's because both “look right.” Always expand the contraction. If it is fails, choose its.

Academic and clinical near-homophones

These pairs dominate college-readiness tests and nursing-program writing samples. Learn them as meaning pairs, not as spelling lists.

Confusable pairCore meaningHealthcare / academic example
affect (usually verb)to influencePain can affect mobility.
effect (usually noun)a resultThe effect of the medication was sedation.

Deeper notes on the highest-yield pairs

Affect vs effect

  • Default TEAS pattern: affect = verb, effect = noun.
  • Memory hook: Affect = Action (verb). Effect = End result (noun).
  • Advanced note (rarely needed): effect can be a verb meaning “to bring about” (effect a change), and affect can be a noun in psychology for displayed emotion. For TEAS, prefer the verb/noun default unless context clearly forces the rare use.

Drill: “How will this drug affect blood pressure?” / “What is the side effect?”

Accept vs except

  • Accept ≈ take in.
  • Except ≈ leave out.
  • Hook: except ≈ exclude.

Drill: “The clinic will accept new patients except on federal holidays.”

Principal vs principle

  • Principal = main thing or person in charge (principal investigator, principal diagnosis in some documentation language, school principal).
  • Principle = rule (ethical principles, scientific principles).
  • Hook: The principal is your pal (person). A principle is a rule.

Complement vs compliment

  • Complement completes (think complete).
  • Compliment praises (think “I like your effort”—social praise).

Stationary vs stationery

  • Stationary = stays (stand still).
  • Stationery = paper (both stationery and paper contain er in many mnemonics: stationERy = papER).

Advice vs advise

  • Advice = noun (ends with soft s sound in many accents).
  • Advise = verb (ends with z sound).
  • Pattern mates: device/devise, practice/practise (U.S. English usually uses practice for both noun and verb—do not overapply British splits on TEAS).

Then vs than; loose vs lose; quiet vs quite

  • Then sequences time: first … then
  • Than compares: more/less/than.
  • Loose rhymes with goose (adjective: not secure).
  • Lose rhymes with choose (verb: misplace/not win).
  • Quiet = silence; quite = degree (quite tired).

Mixed TEAS-style paragraph (error hunt)

Original (with errors): “Your going to loose the specimen if its left their without a label. Accept for the night shift, all nurses excepted the new principle of double-checks. The medication’s affect was quiet strong.”

Corrected: “You're going to lose the specimen if it's left there without a label. Except for the night shift, all nurses accepted the new principle of double-checks. The medication’s effect was quite strong.”

Notice every correction is a real word used for the right job—exactly how TEAS frames many Conventions items.

Strategy checklist for homophone items

Use this rapid process on exam day:

  1. Expand contractions. If they are / you are / it is / who is fails, reject they're / you're / it's / who's.
  2. Name the job of the blank. Possession? Location? Number? Verb of influence? Result noun?
  3. Apply one hook, not five. For affect/effect, use action vs end result. For then/than, use time vs comparison.
  4. Reread the full sentence after inserting your choice. Homophone errors often become obvious only in context.
  5. Watch double traps. Some sentences include two confusable pairs (their/there and too/to). Fix both mentally before selecting the answer that repairs the tested error.

Why this chapter pairs with punctuation later

Homophones like its/it's and who's/whose overlap with apostrophe skills (Chapter 3). If you miss an item, decide whether the issue was possession vs contraction (this section) or a broader apostrophe rule for plural possessives (later). Building both layers prevents double mistakes.

Final TEAS mindset

Spelling conventions are not about being “fancy.” They are about clear, standard written English under time pressure—the same clarity clinical programs expect in notes, care plans, and professional communication. If a word looks familiar, still test it with a replacement phrase or part-of-speech check. That habit turns homophone questions into quick points on the English and Language Usage section. Section 2.3 closes the chapter with the third mechanics family inside Conventions of standard English: capitalization.
