Common English Suffixes

A suffix is a letter or group of letters added to the end of a root or base word.

Unlike prefixes, the primary function of suffixes in English is to change the word’s grammatical class (part of speech). For example, adding the suffix -ful to the noun beauty transforms it into the adjective beautiful.

In this lesson, we will explore the most common suffixes categorized by the part of speech they create: nouns, verbs, adjectives, and adverbs.

1. Noun-Forming Suffixes

These suffixes are added to verbs, adjectives, or other nouns to create nouns. They often indicate a person who does an action, a state of being, a belief, or a relationship.

  1. The suffix -er / -or means “a person who performs an action” or “an agent.” It is added to verbs to form nouns indicating who performs the action. The variant -er is more common with words of Germanic origin, while -or is more frequently used with words from Latin.

    • act -> actor (a person who acts)

  2. The suffix -tion / -sion means “a state, action, or process.” It turns verbs into nouns describing the result or process of an action. The variant -tion is used after “t” or “te” sounds, while -sion is used after “d”, “de”, or “s” sounds.
