Past Simple: Regular and Irregular Verbs

When you want to talk about things that happened and ended in the past, you use the past simple tense. In English, the past simple form of a verb can be either regular or irregular.

Regular Verbs

Regular verbs form the past simple by adding -ed to the base form of the verb.

Structure:

• Affirmative: subject + verb + -ed
• Negative: subject + did not + base verb
• Question: Did + subject + base verb?

Examples:

Base Verb	Past Simple	Example Sentence
walk	walked	I walked to school yesterday.
play	played	She played tennis last weekend.
visit	visited	We visited our grandparents last month.

Note:

• If the verb ends with -e, just add -d → love → loved
• For verbs ending in consonant + y, change y → i + ed → study → studied

Irregular Verbs

Irregular verbs do not follow a fixed pattern in the past simple. You need to memorize them.

Examples:

Base Verb	Past Simple	Example Sentence
go	went	I went to the cinema yesterday.
have	had	She had a sandwich for lunch.
see	saw	We saw a beautiful rainbow.
buy	bought	They bought a new car last week.
