The verb forget is an irregular verb in English. Unlike regular verbs that simply add -ed, forget changes to forgot in the past tense. This irregular form must be memorized as it does not follow the standard conjugation rules.
Irregular verbs like forget/forgot trace back to Old English strong verbs, where vowel changes (ablaut) indicated tense shifts. Over centuries, most verbs regularized to the -ed pattern, but the most frequently used verbs retained their irregular forms because they were too common to change. This is why go/went, see/saw, and break/broke remain irregular today.
When using forgot in writing, remember that it functions as a past tense verb and typically appears with time markers like yesterday, last week, or ago. For example: "Yesterday, she forgot to the store." The past tense form does not change based on the subject — I forgot, you forgot, he/she forgot, we forgot, they forgot.
