Let’s go through each prefix one by one and think of a simple example word that uses it. We’ll match the meaning to make sure our example makes sense.
1.
anti- means “against” → Think of something you’re against, like being *against* freezing — that’s
antifreeze.
2.
bi- means “two” → Something with two wheels is a
bicycle.
3.
dis- means “not, opposite of” → If you don’t like something, you
dislike it.
4.
il-, im-, in-, ir- all mean “not” → Let’s pick
impossible (not possible).
5.
mid- means “middle” → The middle of the day is
midday.
6.
mis- means “wrongly” → If you spell something wrong, you
misspell it.
7.
non- means “not” → Something that’s not toxic is
nontoxic.
8.
over- means “above, too much” → If you eat too much, you
overeat.
9.

pre-school work.
10.

rewrite it.
11.

13.
un- means “not” → Not happy is

14.
under- means “below, not enough” → If you don’t cook food enough, it’s

All these examples fit the meanings given. I double-checked each one to make sure the prefix matches the meaning and the word is real and commonly used.

anti- → antifreeze

il-, im-, in-, ir- → impossible
mid- → midday
