Word forms

Word Forms in English refers to the different grammatical versions of a base word, such as nouns, verbs, adjectives, and adverbs. This guide covers how to create these forms using prefixes and suffixes, explains their typical positions within sentences, and provides exercises to master word families for more precise and diverse communication.

What are Word Forms?

The addition of prefixes and suffixes to words can change their category and function. Some suffixes are used only for nouns, and some are used for verbs. Suffixes can also impart different meanings to words. For example, ‘trainer’ and ‘training’ have the common stem ‘train’, but the suffixes ‘-er’ and ‘-ing’ impart different meanings.
