What is a suffix?
A suffix is a group of letters added to the end of a word to change its meaning or tell when something happens.
Examples:
- play → played
- help → helpful
- jump → jumping
Note
The base word keeps its meaning, but the suffix adds new information.

Spelling rules for adding suffixes
When adding a suffix, the spelling of the base word may change.
Rules and Examples:
- Double the final consonant: hop → hopping
- Drop the silent e: make → making

Note
Say the word slowly and look for spelling patterns you recognize.
