Common mistakes

— 01

Confusing Past Simple

The past simple form is used to describe actions that happened and were completed in the past, e.g., 'Yesterday, I taught a new lesson.' The past participle form, despite being identical in this case, is primarily used in perfect tenses and passive voice, e.g., 'I have taught English for five years,' or 'A new method was taught by the professor.' Misunderstanding their correct contexts leads to errors in tense application and sentence structure.

— 02

Incorrectly conjugating vebs

A second common mistake is attempting to conjugate 'teach' into its past forms using regular verb endings like '-ed'. Because 'teach' is an irregular verb, it doesn't follow the standard pattern of simply adding '-ed' to form its past simple and past participle. Instead of incorrectly saying 'teached,' the correct form is 'taught' for both the past simple and past participle. This mistake often stems from overgeneralizing the rules of regular verb conjugation without recognizing the exceptions that irregular verbs like 'teach' present.

— 03

Misusing in compound tense

Lastly, learners often misuse the past participle form 'taught' when forming compound tenses, particularly the present perfect and past perfect tenses. For example, incorrectly saying 'I had teach the lesson before they arrived' instead of the correct 'I had taught the lesson before they arrived.' This mistake disrupts the intended meaning and temporal understanding of the sentence, as it fails to correctly employ the past participle within the structure of compound tenses, leading to confusion and inaccuracies in conveying the sequence of events or the duration of actions.
