Etymology: The word "bitter" is simple in its construction: it comes from the verb "bite" with the suffix "-er," an agent-noun ending that once turned verbs into doers or things that do the action. The earliest form, Old English "biter," therefore described something that bites, and only later settled into naming the sharp taste that makes you pull back your tongue. The sense is older than the adjective's modern shape, since the same root gives Old Norse-influenced and Germanic cousins across the continent, from Dutch and German to Swedish and Icelandic, all meaning "bitter." The adjective's roots reach back to a shared Germanic ancestor, Proto-Germanic "bitraz," which already carried the sense of sharp, biting taste. Its meaning has held remarkably steady across more than a thousand years, from the Old English texts through Middle English "bittre" to the present day, so the word's story is mostly one of form rather than of meaning.
