cater: [16] Cater is related to French acheter ‘buy’, and originally meant ‘buy provisions’. It comes ultimately from Vulgar Latin *accaptāre, a compound verb formed from the Latin prefix ad- ‘to’ and the verb captāre ‘try to seize’ (source of English catch and chase). This provided the basis for the Anglo-Norman agent noun acatour ‘buyer, purveyor’, which gave English the now obsolete acater.

Losing its a-, this became cater, which until the early 17th century was the word for what we would now call a ‘caterer’. At around the same time cater began to be used as a verb; the first known example of this is in Shakespeare’s As You Like It II, iii: ‘He that doth the ravens feed, yea providently caters for the sparrow’.
