I have a question about the word when. I have read that it can be a conjunction or a relative adverb (either way, it joins two clauses together). Can I ask how do I differentiate between the two?  A few sample sentences are: 1) He graduated from school when he was 22 years old. 2) The risk of theft is higher when you do not install a car alarm system. 3) I remember the day when we first met.

I am not familiar with the idea that an adverb can function as a conjunction at the same time. Here are a couple of sentences that are confusing me.     This is the reason why she left him.   ...and     He was transferred to New York, where he was promoted to a higher level.   The  why, where, when, and how seem to introduce a clause. Therefore, can they also be called conjunctions? If yes, would I be right in assuming that relative adverbs can function as conjunctions at the same time?

I think most folk happily use either "while" or "whilst". I've a vague recollection that at one time "while" indicated the passing of time and "whilst" was essentially the same as "whereas" or "although".  So using while for time passing...     While I was walking down the street the sun was shining.   ... and whilst for whereas/although...     Whilst I was walking down the street I often prefer to hop.   Any views?

Do any one know if we use the word should in any if adverbial clause, so how that affects the sentence? Just my Profs. told me this:  when we add "should", this emphasises the speaker's uncertainty that something will happen.  Take for example.     I'll be at my uncle's house in case you should need to reach me.

Sentence 1： I was told my work was unsatisfactory, at which point I submitted my resignation.  Sentence 2：Sometimes you may feel too frail to cope with things, in which case do them as soon as it is convenient.  I am confused with "which" in the above two sentences. Does it serve relative determiner, rather than relative pronoun? Does "which point" in the first sentence stand for "I was told my work was unsatisfactory"?Does "which case" in the second sentence stand for "sometimes you may feel too frail to cope with things"?  Thank you in advance!

..., whom I mentored during his final semester's project.   ..., whom I mentored on his final semester's project.      Which of these two is grammatically correct? Since I am not talking about the final semester but the final semester's project, I am not very sure about during. Can someone help me with this?

My teacher was explaining how sometimes a comma isn't enough to make a sentence correct, and that sometimes you have to use a semicolon. I am having trouble figuring out when you should use which.   Can someone please explain?

I am always confused about where to put adverbs in sentences. For example, consider the questions below:        Why did they target us specifically?   Why did they target specifically us?   Why did they specifically target us?      I believe all these sentences mean the same. Am I correct? I am always confused about where to put adverbs such as always and specifically, etc. Is there a particular grammar rule for this?  Funny, you see, I can even form the above sentence in different ways.         I always confuse where to put this kind of adverb   Always I confuse where to put this kind of adverb

The 10th and last round of negotiations between Iran and the six world powers was held in Vienna in a bid to strike a final deal. However, after the sides failed to agree on a final deal they decided to extend the negotiations until / by July 1, 2015.   In the original text the preposition until has been written. I am, however, wondering if we could use by instead, if so, is there any difference semantically?  Any help would be greatly appreciated

As a foreign English speaker who never really studied too much English grammar other than the basics at high school, I often struggle to decide what is the correct preposition to use in certain phrases.   At is perhaps the easiest choice to identify, but I find it more difficult to determine when to use on or in.  I know things are on the table or in a box. I’m in a house at street XX,YY.   But are there any rules or ways to find (discounting uncommon exceptions) when to use each form?

When I am using the future tense, why do "while"  and "when" clauses have to be in the present tense?     For instance,       "While I am eating you will be speaking on the phone"   and    "I will be waiting when your plane arrives"   Both sentences are grammatically correct.     But,  doesn't it make more sense to say   "While I will be eating you will be speaking on the phone"  and      "I will be waiting when your plane will arrive."  ?

Sentence 1: I don’t know if it won't rain tomorrow.  Sentnece 2: I don’t know whether it won't rain tomorrow.  Which sentence sound natural to you? Is there a rule that we should use "if" rather than "whether" when the object clause is negative?  Thank you very much!

I know the rule is to use past simple when you specify the time when the described action happened, but I strangely dislike this sentence and I'm not sure if the rule applies:   "It's the best movie I saw this year".  Shouldn't it be: "It's the best movie I've seen this year"?  Please, could you justify your answers? Thank you in advance!  Cheers

I have been wondering what it means when people use "respectively" in, before, and after sentences. For example:     We are looking for a babysitter to pick up and supervise our kids ages   6 and 3, respectively, on Monday and Friday.   I don't know if this person used it correctly, but if they did what does it mean? If they didn't use it properly what would be the proper usage?  Thanks in advance.
