October 2026 - Homophones Study Guide for nursing students in
Homophones sound alike and are spelled differently: principal and principle, complement and compliment, affect and effect, patience and patients. Because they sound identical, reading a sentence aloud will not help — each pair needs its own test.
The pairs that appear most
| Pair | Meanings | Hook |
|---|---|---|
| principal / principle | Chief person or main / a rule or belief | The principal is your pal |
| complement / compliment | Completes something / praise | Complement completes |
| patience / patients | Tolerance / people receiving care | Patients are people, so it is a plural |
| stationary / stationery | Not moving / paper and pens | Stationery has an e, like envelope |
| discreet / discrete | Tactful / separate and distinct | The two es in discrete are separated by the t |
| their / there / they're | Possessive / place / they are | There is a place, like here |
| to / too / two | Direction / also or excessive / the number | Too has an extra o, like an extra amount |
| bare / bear | Uncovered / to carry, or the animal | — |
| peace / piece | Calm / a portion | A piece of pie |
| weather / whether | Climate / if | — |
Homophones that turn up in clinical writing
- patients / patience — the most common of all in nursing coursework.
- oral / aural — by mouth against relating to hearing.
- ileum / ilium — part of the small intestine against part of the pelvis.
- mucus / mucous — the substance is a noun; the membrane is an adjective.
- vain / vein — conceited against a blood vessel.
- course / coarse — a programme of study against rough in texture.
A spellchecker will not catch these. Every homophone is a real word correctly spelled, so the only defence is knowing what each one means — which is exactly why the exam tests them.
Homophone, homograph, homonym
The exam occasionally names these. Homophones sound the same and are spelled differently — to and too. Homographs are spelled the same and may sound different — lead the metal against lead the verb. Homonyms are spelled and sound the same but mean different things — bank as a riverside and bank as a financial institution.
A useful way to hold them: phone is sound, graph is writing. Homophones share sound; homographs share writing.
Choosing between a pair
Worked example
Choose: The (principal / principle) reason for the delay was staffing.
- Identify the job of the word: it modifies "reason", so an adjective meaning "main" is needed.
Principleis only ever a noun — a rule or belief — so it cannot modify anything.Principalworks as both an adjective meaning main and a noun for a chief person.- Substitute to check: "the main reason for the delay" reads correctly.
Principal. When one of a pair can only be a noun, checking what the slot needs grammatically often settles the question before meaning comes into it at all.
Terms to know
- Homophone
- A word sounding like another but spelled differently and meaning something else.
- Homograph
- A word spelled like another but with a different meaning, and sometimes a different sound.
- Homonym
- A word spelled and pronounced like another with a different meaning.
- Context clue
- Information in the surrounding sentence that identifies which word is meant.
