About this worksheet

Spell words with prefixes, suffixes and word bases. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can spell words built with fore-, inter-, super-, trans-, -al and -ion, and words built on audi, ject, dict and duce/duct.
I can see when a base changes before an ending, such as mit to miss or duce to duct, and copy the change to a new word.
I can edit misspelled words in a paragraph by splitting each into its parts.
I can give the reason for a spelling and tell a true reason from an over-broad or invented one.

Words to know

prefix: A part at the start of a word, such as fore- or inter-

suffix: A part at the end of a word, such as -al or -ion

word base: A meaning part such as audi (hear) or ject (throw)

word family: Words that share a base, such as predict and contradict

silent letter: A letter that is written but not heard, such as the c in indict
