What Are Noun Suffixes?

A suffix is a group of letters that you add to the end of a word. When you add a noun suffix, it changes the original word into a noun.

This is a powerful way to make your vocabulary bigger. You can take a word you already know, like a verb or an adjective, and turn it into a noun.

Common Suffixes to Form Nouns from Verbs

Many nouns come from verbs. Here are some of the most common suffixes you can add:

• -tion / -sion: These are very common. They often mean 'the act of' or 'the result of' the verb.
  • Verb: to educate → Noun: education
  • Verb: to decide → Noun: decision
  • Verb: to explain → Noun: explanation
• -ment: This suffix often forms nouns that mean 'the action' or 'the result' of the verb.
  • Verb: to develop → Noun: development
  • Verb: to agree → Noun: agreement
  • Verb: to enjoy → Noun: enjoyment
• -ance / -ence: These suffixes also often mean 'the state of' or 'the quality of' the verb's action.
  • Verb: to perform → Noun: performance
  • Verb: to depend → Noun: dependence
  • Verb: to assist → Noun: assistance
• -al: This suffix can form nouns that refer to an action or process.
  • Verb: to arrive → Noun: arrival
  • Verb: to refuse → Noun: refusal

Common Suffixes to Form Nouns from Adjectives

You can also create nouns from adjectives. These nouns often describe a quality or a state.

• -ness: This is a very common suffix. It means 'the state of being' or 'the quality of being' the adjective.
  • Adjective: happy → Noun: happiness
  • Adjective: kind → Noun: kindness
  • Adjective: dark → Noun: darkness
• -ity: This suffix also means 'the quality of being' or 'the state of being' the adjective. Sometimes the spelling of the adjective changes.
  • Adjective: active → Noun: activity
  • Adjective: possible → Noun: possibility
  • Adjective: generous → Noun: generosity
• -y: This suffix can form nouns referring to a quality or condition, often from adjectives ending in -ous 或 -t.
  • Adjective: difficult → Noun: difficulty
  • Adjective: honest → Noun: honesty

  ✅ I need to make a decision.
• Choosing the wrong suffix: Many suffixes have similar meanings, but they are not interchangeable.
  ❌ The govern-ment made a new inform-ation. (Incorrect suffix for 'information')
  ✅ The government made a new announcement. (Correct suffixes)
• Incorrect spelling changes: Some words change spelling when a suffix is added.
  ❌ He felt much happyness.
  ✅ He felt much happiness. (The 'y' changes to 'i' before '-ness')
