morpheme

Definition

A morpheme is the smallest part of a word that still has its own meaning. For example, in "unbreakable," "un-", "break," and "-able" are all morphemes.

In the word 'cats,' 'cat' is one morpheme and '-s' is another morpheme meaning 'more than one'.

How to teach this in 30 seconds

Try this analogy: A morpheme is like a single Lego brick that has its own special meaning.

Ask your child: In the word 'dogs', what does the 's' part do?

Common mix-up: Kids may think morphemes are the same as syllables. A morpheme is a word part that has its own meaning, like how 'un-' means 'not'.

Examples

  • In 'unhappy,' 'un-' is a morpheme that means 'not'.
  • In 'playing,' '-ing' is a morpheme that means 'happening now'.
  • The word 'play' is one morpheme because it cannot be broken into smaller meaningful parts.

morpheme is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
