WORD FORMATION

Important Rules & Tips for Word Formation

  • Prefix & Suffix: Adding prefixes (un-, re-, dis-) or suffixes (-ment, -tion, -ness) to root words to form new words.
  • Changing Tense & Number: Convert verbs to different tenses or nouns from singular to plural.
  • Use of Synonyms and Antonyms: Sometimes, word formation questions ask to find synonyms or antonyms by changing root words.
  • Compound Words: Form words by combining two or more words (e.g., toothpaste, basketball).
  • Change of Part of Speech: Convert a word from noun to verb, adjective to noun, etc. (e.g., beauty → beautify, strong → strength).

    - -tion, -sion form nouns (creation, decision)
