Better explanation of individual command permissions

Ok I am trying to set up group commands and I do not understand the command itemgive. Does this allow the command line like "item block 54 33"?

It would be nice to have a line by line explanation for each command. The permissions thread is good but this item in particular is ambiguous

Quote from Minotorious

itemgive allows all the following commands:

item ItemName Number Texture
object ObjectName Number Texture
clothing ClothingName Number Texture

That is what I thought! Merci Beaucoup!
