Grammars

Grammar comes from the Greek syntaxis, meaning 'structure' or 'arrangement', and refers to the way items can be combined together. And while I'll use natural language in the examples below, grammars can pertain to sounds, images, drawing images, or even code (the rules for programming languages are good examples of grammars). We can even use grammars as a means of defining other grammars...

So what is a grammar? In essence, it is simply a set of rules which defines a valid sequence of items. For example purposes I'll refer to this sequence as a 'sentence', but remember that it can be nearly any type of item.

If we're given a 'sentence', a grammar can tell us whether it is grammatical correct or not. But more importantly for our purposes, once we have a grammar, we can use it to generate new 'sentences' according to its rules.
