Etymology
Origin of kill1
First recorded in 1175–1225; Middle English cullen, killen, kelle “to strike, beat, kill,” Old English cyllan (unattested); cognate with dialectal German küllen (Westphalian). Cf. quell
Origin of kill2
An Americanism first recorded in 1660–70; from Dutch kil, Middle Dutch kille “channel”
Explanation
To kill is to end the life of some living being or something else. So, you could kill a deer by shooting it with a hunting rifle or kill a bill by voting against it. Hunters kill animals for their meat, and drivers sometimes kill an animal accidentally, or inadvertently kill a plant, simply by forgetting to water it. Certain inanimate things are also said to kill, like poison or disease or drunk driving. In each of these cases, death is caused and life is taken. You can also kill figuratively, as when a school board kills the foreign language program or a thunderstorm kills your hopes of a picnic.
