It's such an important thing, language. The way we use words to express ourselves, describe our surroundings, make sense of what's happening. We look to people's use of language to help us understand how we are supposed to react to a situation; are they using words to express joy, sadness, fear?
Language is a powerful tool. The nursery rhymes sung in childhood to deflect harsh words undersold this power - sticks and stones may break my bones, but words? Words will seep into your consciousness through repetition, they will shape actions with the intent behind them. They legitimise, they ratify the 3am thoughts of self-doubt, the thoughts you feel you can't say in public.
Language changes over time. Certain words become more, or less, nuanced; the definitions warp, sometimes reclaimed by the groups they were once slurs to describe. Language is immensely powerful in dividing people, both through barriers of understanding and through disagreements in ideology.
Language is also incredibly powerful at uniting,
But it is all about intent.
