When I look them up on dictionaries, I find a genereal definition for these words like "it is a place where something is put so that is can be kept safe". So it is pretty hard to distinquish where or how to use them?
I guess these words suggest places used for similar purposes but there are unique collacations with these words that we cannot use one instead of another.
For example I heard museums use the word respotory for the place where they keep the artefacts that they don't exibit currently.But I am not 100% sure.
And I also saw another example of usage on Cambridge Dictionaries Online that "a nuclear waste repository"
An the word depot is used like a terminal where buses that are not on service at night are kept .
I would like to know especially their collacations and which words are prefered in these situations?
1.For example when you go a clothing store and when you could not find the exact size of a pair of shoes you look for among the exhibited ones inside the store, you would want to ask to a sales assistants to make sure if these sizes all was sold out and when you say
"Do you have that size of shoes"
And the sales assistant could asnwer like
" I am not sure.Let me check the .............."
So which word to use appropiate here. This scenerio can apply similar retailer shops like bookshop
2.I would like to know where production factories is kept their raw , semifinished and finished products?
