weedkiller

/wˈidkɪlɚ/ noun

A chemical agent that destroys unwanted plants (weeds) but not wanted ones (crops etc).

Word Origin A straightforward compound: 'weed' from Old English weod (unwanted plant) and 'killer' from cwellan 'to put to death.' The -er suffix makes it 'thing that kills weeds.' The root for 'kill' is PIE *gʷelH-, which also gives us 'quell' (to suppress). Related: 'weed' itself has relatives like 'seaweed' and 'duckweed.'
