Word formation
- Change word class with suffixes: care (noun) -> careful (adjective) -> carefully (adverb).
- Change meaning with prefixes: possible -> impossible; agree -> disagree.
- Recognise noun, verb, adjective and adverb forms.
Key idea
Prefixes and suffixes form new words and change word class (care -> careful -> carefully).
Remember
Suffixes often signal the word class (-ful adjective, -ly adverb).
