Question 1 of 5
Which affix would you add to a root to indicate that there is only one of something?

A.
-able

B.
mono-

C.
pre-

D.
tri-

To determine which affix indicates that there is only one of something, you can break down and analyze the options given.

Option A: The affix "-able" typically indicates that something is capable or worthy of a certain action or quality. It does not imply singularity.

Option B: The affix "mono-" means single or one. Adding "mono-" to a word often indicates that there is only one of that thing. This makes option B a potential answer.

Option C: The affix "pre-" means before or prior to. It does not indicate singularity.

Option D: The affix "tri-" means three. It does not indicate singularity.

Based on this analysis, the correct affix to indicate that there is only one of something is the option B - "mono-".
