Words with a suffix

A suffix is added to a base word that can usually still be seen.

What it is

A suffix is an ending added to a word that already exists: jump + -ed. Spell the base word first and the ending second, and most of these words stop being hard — because you already knew the base.

Watch it built

1
Say the whole word and find the word hiding inside it.
jumped — the word inside is jump
2
Write the base word.
jump
3
Add the ending you heard.
jump + ed → jumped

One more

helping
help + ing → helping
Remember
Find the word inside. Write it, then add the ending.
Ask yourself: “What is the base word underneath?”

Remember

Base word first, then the ending.
