Question 1

Which prefixes are practised on the other prefixes page?

Accepted Answer

The other prefixes page practises non-negative prefixes such as re-, over-, under-, pre-, post- and co-. These prefixes change ideas of repetition, amount, time and cooperation rather than simply making a word negative. Re- can mean again, pre- means before, post- means after, and co- means together. Over- can mean too much, while under- can mean not enough. The sentence tells you which meaning is needed and whether a tense ending is also required. Always test the completed answer in the full sentence.

Question 2

How are other prefixes different from negative prefixes?

Accepted Answer

Other prefixes do not usually mean not or opposite. They add meanings such as again, before, after, too much, not enough or together. For example, reread means read again, preheat means heat before cooking, and co-author means write together with another author. This is why the page should not be treated like negative-prefix practice. You need to connect the prefix meaning with the context of the sentence, then check the natural spelling of the completed word. Always test the completed answer in the full sentence.

Question 3

When do prefixed words need a hyphen?

Accepted Answer

Some prefixed words are commonly written as one word, while others may be accepted with or without a hyphen. You may see variants such as reread and re-read, or cooperate and co-operate. Hyphenation can depend on style, readability and the particular word. On this page, accepted variants are included where both forms are natural. After choosing the prefix, check whether the answer also needs a tense ending, and then use the spelling accepted by the question. Always test the completed answer in the full sentence.
