Grammer provides a structure to our writing and language, allowing us to communicate using an agreed-upon set of rules. It tells us how to turn something we will do into something we are doing, then into something we've done in the past. It also allows us to describe things around us, and using the correct forms of words can help you better communicate with others - and also make sure you get exactly what you are asking for.
When it comes to switching a word from singular to plural, however - or vice-versa - things can get a little complicated. Sure, in general going plural means simply adding an "s" to the end of a word. One cat or multiple cats, one drink or a couple of drinks. Easy, right? Not always.
