topic: vocabulary development on prefixes - JSS1 English Language Lesson Note

Introduction to Prefixes: Prefixes are letters or groups of letters added to the beginning of a word to change its meaning. Understanding prefixes can help us understand the meanings of unfamiliar words and expand our vocabulary.

Suffix is a letter or group of letter added at the end of the word.
