Commonly Confused Words — Grade 8 Practice
0 / 6
Every sentence on this printable has two blanks and one pair of words, so both words get used — one in each blank. The only question is which order. That makes it a harder sheet than it looks, because getting one blank right is not enough.
Both words, one each
Because both words are used, you can check your answer twice: fill the blank you are sure of, then see whether the leftover word fits the other one. If it does not, you have them the wrong way round.
Two rules carry most of these. Affect is the verb and effect is the noun — something affects you and has an effect on you. And an apostrophe almost always means two words squashed together: they’re = they are, it’s = it is.
Question 1
Which words fill the two blanks, in order? I will gladly ____ your invitation, ____ for the late reply.
accept, then except.Accept means to say yes; except means apart from. The sentence says yes to the invitation and then apologises for one thing.
Question 2
Which words fill the two blanks, in order? The loud noise didn’t ____ me much, but it had a strong ____ on my little brother.
affect, then effect. The first blank follows didn’t, so it needs a verb. The second follows a strong, so it needs a noun. The grammar decides it — you do not have to remember which is which.
Question 3
Which words fill the two blanks, in order? If your shoelaces are too ____, you might ____ your shoes while running.
loose, then lose.Loose (two o’s) is the opposite of tight. Lose (one o) means to misplace. The extra o makes the word looser — which is a silly hook, and it works.
Question 4
Which words fill the two blanks, in order? There are ____ students and ____ noise in this class than in the other one.
fewer, then less.Fewer for things you can count — students. Less for things you cannot — noise. You can count students; you cannot count noise.
Question 5 — select all that apply
Select every word below that is a contraction — short for two words. Then press Check.
they’re (they are), it’s (it is) and you’re (you are). The apostrophe is standing in for the missing letters. The other three — their, its, your — show belonging and take no apostrophe, which catches out a great many adults.
Question 6 — put them in order
Click these steps in order — the test for it’s versus its.
Substitute, check, then decide. “The dog wagged it is tail” is nonsense, so it is its tail. This one test replaces the whole rule.
Think about it
Both words get used in every sentence on this sheet. How does that help you check your answer?
Affect is a verb and effect is a noun. Write one sentence using each.
Why do its and your take no apostrophe when they show belonging, but the dog’s tail does?
Try the “it is” test on: Its been a long day. Is it right?
