Word-form Changes in English

Understanding Word-form Changes

In English, words can change form to indicate different grammatical meanings. These changes can show number, tense, degree, and more. Understanding these changes is essential for mastering English grammar.

Number

Number refers to whether a word is singular or plural. Here are some common patterns:

• Regular Plurals: Add -s or -es (e.g., cat → cats, box → boxes).
• Irregular Plurals: Change the word form (e.g., child → children, mouse → mice).

Tense

Tense indicates the time of action. Here are some common tense changes:

• Present to Past: Add -ed for regular verbs (e.g., walk → walked).
• Irregular Verbs: Change the word form (e.g., go → went, have → had).

Degree

Degree is used to compare adjectives and adverbs. Here are some examples:

• Comparative: Add -er or use "more" (e.g., tall → taller, beautiful → more beautiful).
• Superlative: Add -est or use "most" (e.g., tall → tallest, beautiful → most beautiful).
