Caterer

The word caterer, a provider of food or provisions, comes to English in the mid-15th century. The verb ‘to cater’ (to provide food for) comes to English around 1600 from Middle English catour (buyer of provisions) from Old French achater (to buy), from Latin accaptare (ad = to + captare = to take, to hold, to strive), and Greek kaptein (to gulp down). The Proto-Indo-European root of the word caterer is kap (to grasp).
