Prefixes: Definition with Examples

Prefixes are the letter/s which sit before a stem to make new words. These letters are also called affixes.

Affixes generally have no meaning by their own but can form meaningful words by sitting before/after the stems. In the case of prefixed words, affixes sit before the stems of the words.  

“A prefix is an affix which is placed before the stem of a word.” – Wilson (2011)
A prefix is “a letter or group of letters that is added at the beginning of a word to change its meaning.” – Merriam Webster.

Example:

  • Prefix = ‘fix’ is a stem and ‘pre’ is a prefix which changes the meaning of the stem and creates a new word.
  • Antibiotic
  • Awake
  • Symphony
  • Hemisphere
