Varieties of Word Prefixes – Their Explanation and Instances

Grade 10
May 17, 2023


Prefix: A prefix is an affix attached to the beginning of a word, base, or phrases and produces a derivative comment or an inflectional form.




Rules that you must remember while Using Prefixes:

  1. The spelling of the base word never changes upon adding a prefix.
  2. Use a hyphen between the prefix and the root word in the following cases:
    1. When attached to a numeral (pre-1965, post-2010).
    2. When connected to a proper noun (un-American, ex-President).
    3. After the prefixes ‘ex-,’ ‘quasi-,’ and ‘self-’ (self-respect, quasi-static).
    4. To separate letter combinations to avoid mispronunciation (co-worker, anti-intellectual).
    5. To prevent ambiguity (re-cover vs. recover, re-lay vs. relay).
    6. When the root consists of two words (post-World War II, non-English speaking).
    7. When the prefix stands alone (micro- and macroeconomics).
