4th Grade Suffixes -ful, -less, and -ness worksheets

About this worksheet

Suffixes -ful, -less, and -ness change how a base word works by adding meaning at the end matters in fourth grade because spelling work now connects word meaning, word parts, and editing accuracy. Fourth graders may hear the final syllable but still choose a suffix that changes the meaning in the wrong direction, or forget to change y to i in words like happiness and beautiful. This worksheet keeps the focus on one spelling pattern at a time, and every wrong choice is a mistake a real speller might make, so children cannot get credit by ruling out silly answers.

Students choose the suffix that gives a meaning, spell words with suffixes, complete sentences, and spot the correctly spelled word. Support versions use more familiar words and fewer choices. Standard versions add harder words, and challenge versions add longer words and the cases where the pattern does not apply. Ask your child to say the word, mark the meaningful part or spelling change, and then check whether the written form still matches the meaning. That process is slower than guessing, but it builds spelling habits that transfer to real writing.

What your child will learn

• Use -ful to mean full of
• Use -less to mean without
• Use -ness to make a noun meaning state or quality
• Change y to i before a suffix when a consonant comes before the y
