Understanding root words with prefixes and suffixes is one of the easiest ways to improve your English vocabulary. Most English words are formed by combining a root word with a prefix (added at the beginning) or a suffix (added at the end).
For example:
- re + write → rewrite (write again)
- read + able → readable (can be read)
Learning this structure helps you understand and create new words easily.
👉 To understand the basics, explore Root Words in English.
A root word is the basic part of a word that carries its main meaning. It cannot be broken down into smaller parts.
👉 Example:
- act → action, actor, active
- write → writer, rewrite, writing
