Not only do humans have an inordinate propensity for killing things… As you will see from this page they also have an inordinate propensity for creating words about killing things.
Words concerning death, destruction, extermination and deliberate killing usually end in the prefix -cide. The -cide ending came to us from Middle French and originates in the Latin -cida, from caedere, meaning “to kill”.
NOTE: While some -cide words refer exclusively to the act of killing a specific thing or person (e.g. herbicide); others can refer alternately to the act itself or to the person performing the act (e.g. homicide).
