What is a suffix?

Suffixes are little words added to the end of a word like -ed or -ing.

If a word is short and ends in a vowel and a consonant, the last consonant is doubled before the suffix.




If the word is followed by two consonants, such as in the word jump, the last consonant is not doubled - jumping.

Here are some examples of double letter suffixes:

Fatter, saddest, dropped, patting and running.
