An idiom is a funny kind of phrase that is more like a word.
- An idiom is a funny kind of phrase that is more like a word.
- Like a word, made out of phonemes or sub-components, the whole becomes more important than the parts.
- It evolves as a unit, away from its original literal meaning as a string of components.
- It transcends from being a whole that is just the sum of the parts, to being something else that is different and distinct and can evolve differently.
- Not too dissimilar from how "black bird" and "blackbird" are two semantically different things, with different evolutionary pressures.
