If you have any doubts or questions Hello everyone, Recently I got an email of an English course and its details. Everything was well explained untill I saw the following sentence at the end: If you have any DOUBTS, just let me know. I learnt a while ago that the word "doubt" in English has to do with beliefs and not to somenthing you want an explanation for such as a meaning of a chunk or a word you don't know the meaning, in other words, a question. So, wouldn't it be "If you have any questions...? Doubts would suit just a sentence like that: I doubt he will get richer than Bill Gates. Fell free to correct me if I'm wrong. Thanks in advance for you help.

Is there any difference between Whilst, Whereas and While? Provided these three words mean the same, I don't think there is a huge difference between them, if so, would anyone be able to show or explain what are they? For example: I was watching TV while they were hanging out in the backyard. There were three guys running to school whilst was waiting for my girlfriend inside my car. I can listen English podcasts whereas I'm going to work. Thanks in advance.

Which would b the difference between to miss ans to lost? I have studied English abroad for one month and once I was talking to a native about one bus I had lost, after saying that, he made a correction right away saying that I missed the bus and not lost the bus. Thank you.

I've got a questuon Could anyone explain the differences between back up, to assist and to support? Which contexts are more appropriate to use one and the others? One example would be: I have decided to back you up. I have decided to support you. I have decided to assist you. Thanks in advance.
