Inflection (or inflexion) is a piece added to a word to express variations in grammar. The added bits are called affixes. They are prefixes (in front), suffixes (at the end) and infixes (in the middle). They are added to the root, the part of the word which does not change.

Examples:

  • Write, wrote, written are tenses of the verb to write. Inflecting a verb is called conjugation.
  • Sing, sang, sung
  • Foot, feet is a noun inflected for number. Inflecting a noun is called declension.
  • Mouse, mice
