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

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.
Question 1 of 4
Which sentence is correct?
Choose one answer, then check it.
View the Answer and Explanation
Correct answer: B. The principal reason for the change was patient safety.
Principal is the adjective meaning main, and patient safety refers to the safety of the people receiving care. Principle is only ever a noun meaning a rule, and patience is the quality of being tolerant.
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.
Question 2 of 4
Choose the correct word: The consultant paid her a ____ on the quality of her documentation.
Choose one answer, then check it.
View the Answer and Explanation
Correct answer: B. compliment
Praise is a compliment with an i. A complement completes something — as a full staffing complement does — and the remaining two are simply misspellings of either word.
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.
Principle is only ever a noun — a rule or belief — so it cannot modify anything.
Principal works 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

What the HESI asks most
The same core ideas appear in different wording. If you can answer these without stopping to think, you have what this section requires.
Which word correctly completes the sentence?
Work out what the slot needs grammatically, then apply the hook for that pair.
Which sentence uses the word correctly?
Substitute the definition into the sentence and see whether it still makes sense.
What is a homophone?
Words that sound alike and are spelled differently. Homographs share spelling instead.
Question 3 of 4
What is the difference between a homophone and a homograph?
Choose one answer, then check it.
View the Answer and Explanation
Correct answer: B. Homophones share sound; homographs share spelling.
Phone means sound and graph means writing, which is the whole distinction: to and too are homophones, while lead the metal and lead the verb are homographs. Neither category is restricted to a particular part of speech.
Key points
Homophones sound identical, so reading aloud cannot help — each pair needs its own test.
The principal is your pal; a principle is a rule.
Patients are people; patience is what you need with them.
Which sentence uses stationary and stationery correctly?
Choose one answer, then check it.
View the Answer and Explanation
Correct answer: B. The trolley remained stationary while she collected stationery from the cupboard.
A trolley that is not moving is stationary with an a, while paper and pens are stationery with an e — like envelope. Only the second choice gets both slots the right way round.
