Glossary

Morpheme – any part of a word which carries distinct meaning. For example the word ‘worked’ can be broken into two morphemes: ‘work’ and ‘ed’, meaning the action took place in the past. In this case ‘ed’ is a suffix as it comes after the stem (main word). A morpheme like ‘re’, as in ‘rework’, is called a prefix as it comes before the stem.

Stem – the main part of a word to which a morpheme / morphemes can be added. For example in the word ‘uncomfortable’, ‘comfort’ is the stem, ‘un-‘ is the prefix, and ‘-able’ is the suffix.
