The verb decide has deadly interesting origins. Though it came through Middle English deciden, Old French decider, and Latin decidere, you can tell that there's the prefix de-, kind of meaning "off". This was in the language as far as etymologists can trace it, and is either from Etruscan or Proto-Indo-European. It's the other part of decide that's surprising: -cide. Yup, as you may have guessed, this is the same -cide present in words like homicide, suicide, regicide, fratricide, genocide, and all those other euphemistic terms for nasty kinds of death. All the roots trace to the Latin verb caedere, meaning "to cut". The death-related words are connected because of the correlation between "cut" and "kill", a side meaning which later evolved from the word, and decide is connected because when you make a choice, you cut out all the other possible choices. So it sort of makes sense, right? Caedere comes from Proto-Italic kaido, from Proto-Indo-European kehid, which meant something more like "strike".
