Invented Languages and the Science of the Mind

This difference is found in language after language. Generally, grammatical words are very short, they tend to be simple syllables, and they are frequent. They signal grammatical ideas, like definiteness and tense. Core meaning words tend to be longer, more complex in their syllable structure, each one is less frequent....

One of the properties of grammatical words is that they don’t have fixed positions in a sentence. If you look at the sentence you’ve just read, you can see grammatical words interspersed quite randomly through it. Here it is repeated with those words in bold.
