Could you please provide the options or context for me to be able to determine which one is grammatically correct?
No, because there's no verb. You might say "The neck is a tad bit queer," however.
The sentence "Is gratitude seems to be a vanishing virtue" is not grammatically correct. It should be written as "Gratitude seems to be a vanishing virtue."
Both are correct, but "There are a lot of" is more commonly used when referring to a plural noun. For example, "There are a lot of books on the shelf."
The phrase "registrations are in progress" is grammatically correct. The subject "registrations" agrees with the verb "are" and the prepositional phrase "in progress" correctly describes the state of the registrations.
Yes it is correct to say "Have a wonderful Holiday."
Yes it is.
No, the correct phrase is "in retrospect." "In retrospect" means looking back on a past event or situation with understanding gained from later knowledge or experience.
You should say for your convenience it is *gramatically correct-*just means correct
Yes.
Yes, there is a verb and and a noun and they are in the same tense therefore it is gramatically correct.
That's not even a complete sentence. The words TO, SAT, THIS, PEOPLE and IS can not be combined in any way to make a grammatically correct sentence. ------------------------------------------------------------------------------------------------------------- Assuming the question should be Is it gramatically correct to say, "This people is..."? then it is not correct. One should say, "These people are...".
I don't see why not although beginning a sentence with 'or' is unusual.
No. It would be better to just say those or these.
Yes. "She has no idea that you are even here." is a correctly formed, gramatically correct sentence.
No. You would normally say something like higher up.
No. I would say: "You and her will begin to ship the product".
