A suffix is a group of letters added to the end of a word that changes its meaning or grammatical function. Suffixes can modify the root word to indicate a change in tense, form, or meaning, and they often adjust the word’s part of speech (e.g., from a noun to an adjective).
Types of Suffixes and Their Effects
- Changing Grammatical Role: Suffixes can change a word from one part of speech to another.
- Example: beauty (noun) → beautiful (adjective)
- Effect: The suffix -ful turns the noun beauty into the adjective beautiful, indicating that something possesses beauty.
- Indicating Tense or Plurality: In verbs and nouns, suffixes can signify tense, number, or comparison.
- Example: walk → walked (past tense)
- Example: book → books (plural)
- Effect: The suffix -ed indicates a past action, while -s shows more than one.
- Adding Degree or Intensity: Suffixes can indicate a comparative or superlative degree.
- Example: small → smaller → smallest
- Effect: The suffixes -er and -est show comparisons between items or qualities.
- Changing Meaning: Suffixes can completely alter the meaning of a word.
- Example: help → helpless
- Effect: The suffix -less means “without,” changing help (assistance) into helpless (without assistance).
- Creating New Words: Suffixes can expand vocabulary by creating words with new meanings.
- Example: act → action, actor, active
- Effect: Each suffix (-ion, -or, -ive) creates a new word with a distinct meaning related to the root word.
