Identify base words, prefixes, and suffixes

What is a Base Word?

The base word is the main part of a word. It’s like the root of a tree! We can add things to the base word to make new words. The base word has meaning on its own.

Here are some examples:

  • play (We can play games!)
  • jump (I can jump high!)
  • happy (The sun makes me happy!)
  • help (I like to help my friends.)
What is a Prefix?

A prefix is a group of letters that we add to the beginning of a base word. It changes the meaning of the word. Think of ‘pre’ fix as ‘before’ fix.

Here are some common prefixes:

  • un- (means ‘not’)
  • re- (means ‘again’)
  • pre- (means ‘before’)
  • dis- (means ‘not’ or ‘opposite of’)

Let’s see some examples:

  • unhappy (not happy)
  • replay (play again)
  • preview (view before)
  • disagree (not agree)
What is a Suffix?

A suffix is a group of letters that we add to the end of a base word. It also changes the meaning of the word or how it’s used. Think of ‘suff’ as stuff at the end.

Here are some common suffixes:

  • -ing (means ‘happening now’)
  • -ed (means ‘happened in the past’)
  • -er (means ‘someone who’ or ‘more’)
  • -est (means ‘the most’)

Let’s see some examples:

  • playing (happening now)
  • jumped (happened in the past)
  • teacher (someone who teaches)
  • happiest (the most happy)
