Simple Origin or Background Explanation

The verb shake is an irregular verb in English. This means it does not follow the normal pattern of adding -ed to form the past tense.

Many regular verbs work like this:

• Walk → Walked
• Jump → Jumped
• Clean → Cleaned

But shake is different:

Verb Form	Word
Base Verb	Shake
Past Tense	Shook
Past Participle	Shaken

Because English has many irregular verbs, learners often mix up the past tense and past participle forms.

The Difference Between Shook and Shaken

Examples:
