Commonly Confused Words

A large share of CSE verbal items boil down to one question: which of two look-alike or sound-alike words fits this blank? These "wastong gamit" items in English cost you points only if you rely on sound, because the confusable pairs sound identical or nearly so. The fix is a memory hook for each pair: a short, sticky rule you can recall in two seconds. This lesson gives you the full working list, grouped by how the pairs differ, each with a hook and an example.

Grammar-role pairs: same idea, different job in the sentence

Pair	Rule	Hook	Example
its / it's	its = possessive; it's = it is / it has	The apostrophe stands for the missing letter of "is."	The office updated its logo. It's ready for printing.
your / you're	your = possessive; you're = you are	Expand it: if "you are" fits, use you're.	You're required to bring your ID.
their / there / they're	their = possessive; there = place or existence; they're = they are	There contains "here" (place).	They're sure their documents are there.
whose / who's	whose = possessive; who's = who is	Same apostrophe trick.	Who's the analyst whose desk is by the window?
then / than	then = time or sequence; than = comparison	Then/when rhyme (time); than/comparison share the letter a.	Finish the draft, then submit it; it is better than the old one.
to / too / two	to = direction or infinitive; too = also or excessively; two = 2	Too has an extra o, meaning "extra."	The two clerks went to the seminar too.

Worked example 1. Choose the correct word: "The agency will announce ______ decision once ______ final." (a) it's / its (b) its / it's (c) its / its (d) it's / it's First blank is possessive (the agency's decision): its. Second expands to "it is final": it's. Answer: (b).

Worked example 3. Choose the correct sentence. (a) Express lane: 10 items or less. (b) The clinic saw less patients this week. (c) The clinic saw fewer patients this week. (d) There were less complaints than last month. Patients and complaints are countable, so fewer is required. Answer: (c).

Worked example 4. Choose the correct verb: "Feeling dizzy, the examinee ______ down on the clinic cot for an hour." (a) laid (b) lay (c) lain (d) lays The examinee reclined (no object), so we need the past tense of lie: lay. Laid is the past of lay, which requires an object. Answer: (b).

Common traps

• Its/it's in headlines and signs: exam sentences copy real-world errors like "The company celebrated it's anniversary." Expand the contraction to test it.
• Effect as a verb: "to effect change" is valid and means to bring about; do not auto-mark effect-as-verb wrong when the object is change, reform, or a solution.
• Lay in the past: "She lay on the couch" is correct past tense of lie, even though it looks like the verb lay. Time-check before judging.
• Less with numbers of time and money: "less than 30 days" and "less than ₱500" are accepted because the quantity is treated as a single amount. The strict fewer rule applies to counted objects (fewer forms, fewer employees).
• Then/than in fast reading: under time pressure, the eye slides over the vowel. Slow down whenever a comparison word (better, more, rather, other) appears; it demands than.
• Council/counsel and personnel/personal in office memos: the exam loves these because they appear in real government correspondence.
• Alright and irregardless: the standard forms are "all right" and "regardless."

Exam strategy

1. Identify the blank's job first: does it need a noun, verb, or adjective? That alone settles affect/effect, advice/advise, device/devise.
2. Apply the count test for fewer/less, number/amount, many/much: can you make it plural? If yes, use the countable word.
3. Expand every contraction: it's = it is, you're = you are, who's = who is. If the expansion breaks the sentence, choose the possessive.
4. For lie/lay, rise/raise, sit/set, ask: is there an object being acted on? Object present means lay/raise/set.
5. Keep a personal error log while reviewing. Most test-takers confuse only five or six pairs consistently; drilling exactly those pairs is the highest-yield hour of verbal prep.

Diction items are pure preparation. Every pair you lock in with a hook is a guaranteed point, no reasoning required on exam day.
