Common mistakes

— 01

Confusing forms

Mistake. A common error is confusing the past simple form of a verb with its past participle form, or vice versa. This is particularly noticeable with irregular verbs. For the verb 'redo,' the past simple is 'redid,' and the past participle is 'redone.' A mistake would be using 'redone' when a simple past action is needed, or using 'redid' in a perfect tense that requires the past participle. Incorrect. I have redid my homework. (Here, the past participle 'redone' should be used.)

— 02

Incorrect Formation of Past Participle

Mistake. Another mistake is Incorrect Past Participle by adding a regular past tense ending (-ed) to irregular verbs. Since 'redo' is a regular verb when it comes to its past forms, a similar mistake would be applying this error to irregular verbs or misapplying it to verbs like 'redo' by creating non-existent forms. Incorrect Example for a Similar Verb. He has swimmed in the ocean. (The correct past participle is 'swum' for the verb 'swim.')

— 03

Misuse in Passive Constructions

Mistake. Misusing the past simple and past participle forms in passive voice sentences can lead to grammatical errors. The past participle should be used in passive constructions, but sometimes the past simple is mistakenly used instead. Incorrect. The task was redid by her last night. (This uses the past simple 'redid' instead of the correct past participle 'redone' for a passive structure.) Correct. The task was redone by her last night. (This correctly uses the past participle 'redone' in a passive construction.)
