Prefixes ( 1)
We use prefixes to change meaning. They never change the part of speech. (Most suffixes change the part of speech.)
• Many prefixes give a word a meaning which is the opposite or negative of the original. For example, we can use the prefixes dis or un:
dis + appear - disappear
un + tie - untie
• We use il instead of in with words that begin with l:il + legal = illegal
• We use im instead of in with words that begin with m or p:im + polite - impolite
• We often use ir instead of in with words that begin with r:
ir + responsible = irresponsible.
• Some common mistakes are:
You must disconnect the cables first.
/ They expelled him for misbehaving.
• Note that many words with a prefix have a base part that never exists on its own. Here are examples: immediate, incontrovertible, uncalled-for
Add a correct prefix to the following words.
Don't write in capitals
