A pride of lion was seen nearby.
No. There is one word wrong. The sentence should be: I thought of you when I saw it.
No, I think the correct way is- Is this the first time you've seen it?
Yes, it's the correct use of the word 'wise' but the sentence needs a comma after the initial phrase: As far as you have seen, your seniors are so wise.
They are both correct.
Yes, the sentence is mostly clear in its meaning. However, to improve clarity, you could consider rephrasing it slightly to "Her jaw dropped as if she had seen the devil."
NEVER. 'I seen it' is grammatically incorrect and sounds awful when spoken. Please - never, ever, ever, ever say 'I seen it'. The correct sentence would be 'I saw it'.
I have ever seen a sentence " Eric's father ordered himnot to stay out late again." at a grammar test before."not to stay" is correct answer.
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.
Your sentence is correct.
It is incorrect. You may use "You saw him yesterday" as a statement or "You saw him yesterday?", as a question
"How are you" is a correct sentence.
