We know that words over time, almost all words, especially nouns, verbs, adjectives and adverbs, develop different meanings. And we have some words that have more than a hundred meanings. But contronyms develop opposite meanings. Take the word 'out': just a three-letter word; sometimes an adverb, sometimes a preposition or a particle. When the sun is out, you can see it; when the lights are out, then you can't see them. So it is both visible and invisible."
"Right, and fast can mean moving quickly or firmly in one place. And that's the rarer meaning, but you 'hold fast' to something, it means you stay with it, whereas 'she ran fast' would be somebody moving rapidly. And similarly, 'bolt' —to secure in place, and then also to dart away, so it's both still and moving. 'I'll bolt the door' — you're securing it in place so that it won't move. And 'Did you see the horse bolt, or the bolt of lightning?' That has to do with very rapid movement."
