Guide on/in Preposition

[kl004535]

Dear Teachers,

I know prepositions in time and space can be used metaphorically in showing abstract relation between two entities.

Frankly speaking, I am totally confused about it. For example,

I do not know which one of them I should put in the phrase below:

Guide (on/in/at) preposition

I am much obliged to you for your guidance.

Thanks

I'm not quite sure I know what the question is here! Are you writing a guide, and the subject will be prepositions?

If that is the case then you are writing a "Guide to Prepositions".

Confusing, eh?!

Please note that a preposition is used before a noun or pronoun (called object of the preposition) that establishes a relationship with another word of the sentence to impart a temporal meaning to the whole sentence. So in that sense preposition is a very tricky word.
There are hardly any rules as to when and where to use which preposition except some guide lines available for the basic prepositions such as in, on and at, which you can study from a good grammar site on the Web. Here is one such site:Prepositions of Place: at, in, on
However to become conversant and gain confidence, the only way to learn is by looking them up in a dictionary, reading a lot in English (literature), learning useful prepositional phrases off by heart (study tips) and above all doing a lot practice on uses of different prepositions which includes verifying the correctness of their uses. You can use this forum effectively for that purpose.
