I have / I've just seen you do it. (so none of your variants).
No. There is one word wrong. The sentence should be: I thought of you when I saw it.
A frequently used and very inccorect usage of the word seen is in its past tense form; Wrong I seen that movie. Correct I saw that movie or I have seen that movie.
The correct version is "I saw her yesterday."
It is true that we prefer "you and Ellen" to "Ellen and you" as a compound subject. However Ellen and you" is not grammatically wrong, and indeed is perfectly acceptable as a compound object: "I saw Ellen and you talking together."
Both MAY be correct, according to context. For example, as the object of a verb or a preposition, only "me and my team" is correct: " You saw me and my team win the game," or "The community provided support for me and my team." But as the subject of a verb, only "my team and I" is correct: "My team and I won the game."
The correct grammar is "Gary and Louise saw a deer last week."
"Spotted these people dancing zumba" is not correct grammar but the correct grammar is "I saw these people dancing Zumba"
"Saw that picture" is correct. Use "saw" as the past tense of "see."
"You saw him" would be correct in this context.
It is correct to say that you saw it.Never say 'you seen it'.If using the word seen, it must be accompanied by the word have or had. I have seen is the present perfect tense and had seen is the past perfect tense.you saw - Affirmative; you did not see - Negative; did you see? - Interrogative.
The phrase "is you seen" is not proper English grammar. It appears to be a grammatical error, as "is" is the present tense form of the verb "to be" and "seen" is the past participle form of "see." A correct phrasing could be "have you seen?" or "did you see?" depending on the context.
The correct grammar is "He was seen by you." This is the passive voice construction.
Yes, as the object of a verb or a preposition: I saw Bob; I saw her; I saw Bob and her. Some people think "her and Bob" sounds better, but it is not any more correct. There is nothing wrong grammatically with the construction 'Bob and her' as the object of a verb. Whether it sounds better or worse than 'her and Bob' is a question of usage or taste, not of grammar.
It is incorrect. You may use "You saw him yesterday" as a statement or "You saw him yesterday?", as a question
No. It would be either "you saw" or "you have seen" or "have you seen?" depending on context.
If you mean is it based on real events, the answer is no.
In some varieties, the past tense form is used as a past participle, in place of the different past participle which is used in standard varieties. So this example may be used in some dialects, but it is not grammatical in standard English.
