Prefix and Suffix Crossword

Read each clue and write the answer in the squares that start at its number, one letter in each square.

This grid is wider than a phone screen, so it scrolls sideways. It prints whole.

Tap a square, and its clue shows here.

Across

Down

Type in a square and the next one takes over. Tap the same square again, or press Space, to switch between Across and Down. Arrow keys move around the grid, Enter goes to the next clue, and a clue takes you to its squares.

Print gives 2 pages on Letter or A4: the puzzle with its clues, then the answer key. The squares print 10 mm wide. For a PDF, choose Save as PDF in the print window.

A share link holds the puzzle number and these settings, nothing you typed.

How this list was compiled: Clues written for this site for grades 2 to 6. Each built word was read in its English Wiktionary entry (CC BY-SA 4.0), which names its prefix or suffix and its base word; the meanings of the word parts follow their Wiktionary entries and the grammar terms follow English Wikipedia, in October 2026. Spellings are American. Words that only look as if they hold a prefix were left out. Licence: own work

Questions and answers

What grade is the prefix and suffix crossword puzzle for?

Easy Prefix and Suffix Words suits grades 2 to 4, with answers such as Unlock, Redo and Hopeful. The five sets of built words suit grades 3 to 5, and Word Part Terms grades 4 to 6. These bands are our judgment.

Does the prefix and suffix crossword have an answer key?

Yes. The answer key is the last sheet of each print, with the grid filled in. Free, with no sign-up.

What do the prefixes un- and re- mean?

Un- means not, as in Unhappy, or reverses an action, as in Unlock. Re- means again, as in Refill. All three words are in the easy set.

What do the suffixes -ful and -less mean?

-ful means full of, so Careful is full of care. -less means without, so Careless is without care. Both words are answers, clued just that way.

What is the difference between a prefix and a suffix?

A prefix is placed before the base of a word and a suffix after it. Both are affixes. Prefix, Suffix and Affix are answers in Word Part Terms.
