Prefixes

Meaning of Prefixes

The letters which we add to the beginning of certain words to give it a different meaning is referred to as prefixes. By attaching a prefix, usually, a new word is formed which means the opposite to the existing word. A prefix can also be used to denote the time, place and manner of the word. Some examples of how prefixes are used:

  1. I’m sorry I was unable to reach on time.
  2. Non-payment of rent could result in the tenant being asked to leave the house.
  3. Have you ever met an extraterrestrial being? (meaning a being from another planet)
  4. The curry was overcooked and quite tasteless.
