The second key feature of language is generativity (also called productivity). Generativity means that we can create and understand an infinite number of meaningful sentences and utterances. Every language has a fixed or finite number of basic sounds, letters, and words. But a fluent person can generate an infinite number of completely novel sentences with those sounds, letters, and words.
Symbolism | Generativity |
---|---|
Words “refer” to other things What a word “refers” to is often its meaning | We can create and understand an infinite number of meaningful sentences |
This is a great way to break down both meanings.
