Expert writing Tips

Best practice

Always use the correct past participle form of the verb "see", which is "saw" for simple past tense and "seen" when used with auxiliary verbs like "have", "had", or "be".

Common error

Avoid using "seen" as a simple past tense verb. "Seen" requires an auxiliary verb such as "have", "has", or "had". The correct simple past form is "saw".

Linguistic Context

The phrase "they seen" functions as an incorrect verb form. Ludwig AI identifies this as a grammatical error because "seen" is a past participle and requires an auxiliary verb (e.g., "have", "has", "had") to form a correct verb phrase.

Ludwig's WRAP-UP

The phrase "they seen" is a common grammatical error, as identified by Ludwig AI. The correct forms are "they saw" (simple past) or "they have seen" (present perfect). Using "seen" without an auxiliary verb like "have", "has", or "had" is incorrect and should be avoided, especially in formal writing.
