  • Suffix Example: The suffix -ful added to help creates helpful, which means “full of help.”

2. What is the definition of prefix and suffix words?

Prefix and suffix words are words created by attaching an affix (a prefix or a suffix) to a root word. This process helps students understand word formation and the meaning of new vocabulary.

  • A prefix is a word part placed at the start of a word (e.g., re- in the word replay).
  • A suffix is a word part placed at the end of a word (e.g., -less in the word fearless).
