Common mistakes

— 01

Incorrect Verb Form

One common mistake is applying the regular verb rule (adding -ed) to irregular verbs. Since 'stamp' is a regular verb and correctly becomes 'stamped' in both its past simple and past participle forms, the mistake would be assuming it changes irregularly. For example, saying 'stampt' or 'stomped' (confusing it with 'stomp') instead of 'stamped.'

— 02

Misuse in Perfect Tenses

Another mistake is incorrectly using the simple past form when the past participle is needed, especially in perfect tenses. For instance, saying 'I have stamp the letter' instead of the correct form 'I have stamped the letter.' This error stems from not distinguishing between when to use the simple past and when to use the past participle.

— 03

Confusion with Similar Sounding Verbs

A third mistake involves confusing 'stamp' with similar-sounding verbs that may have different past and past participle forms, such as 'stomp.' Users might mistakenly apply the pattern of an irregular verb to 'stamp,' leading to incorrect forms. For example, treating 'stamp' as if it were irregular like 'sing' (sang, sung) and saying 'stamp, stampt, stampt' or inventing forms that mimic irregular patterns, instead of the correct 'stamp, stamped, stamped.'
