English Grammar: Prefixes

Prefixes

A prefix is a letter or a group of letters added to the beginning of a word to form a new word with a different meaning.

Types of Prefixes

• Denotative prefixes: Change the meaning of a word without changing its grammatical function.
  • Examples: un-, re-, de-, non-
• Connotative prefixes: Change the emotional tone or attitude of a word.
  • Examples: sub-, super-, anti-, pseudo-
• Distributive prefixes: Indicate distribution or separation.
  • Examples: bi-, tri-, quad-, multi-

Common Prefixes

• re-: again, repetition (e.g., redo, rewrite)
• de-: removal, reversal (e.g., defrost, dehydrate)
• non-: negation, absence (e.g., nonstop, nonfiction)
• sub-: under, below (e.g., submarine, subscript)
• super-: above, over (e.g., supermarket, supervisor)
• anti-: against, opposite (e.g., antibacterial, antiwar)
• post-: after, later (e.g., postoffice, postgraduate)
• pre-: before, earlier (e.g., preheat, prehistoric)
