It conveys meaning. It marks the following word as a noun, and also as a singular noun. It also denotes that the object spoken of is not singled out for attention; it suggests that it is one of a group which are indistinguishable from each other for the purposes of the sentence. "Bring me a screwdriver from the toolbox" means that the person wants one screwdriver, no more, but it can be any one of the screwdrivers in the toolbox. It is implied that there are two or more screwdrivers in the box. "Bring me a Phillips screwdriver from the toolbox" means again that the person wants only one screwdriver, but it can be any one of the Phillips screwdrivers in the toolbox. There may be screwdrivers which are not Phillips, but there are certainly two or more Phillips ones.
