- Charred. That burned blackened stuff. See? Nobody said care.
- Char star (non-C people won't get this) Care star sounds like it belongs in a pink pony book.
- Char sounds like slang for 'character'. But characters != char. Char is a numerical value, while character is something dragged out of some (human) language.
I also know people who pronounce char like 'car'. Those people don't bother me as much as the ones who say 'care'. Anyway, I wrote this blog post mostly because I didn't know what else to write.
