dapple [dapple 词源字典]: dapple: [14] Dapple is a puzzling word. It is presumably derived from or linked in some way to its contemporary dapple-grey (although this has never been proved), which has formal and semantic links with several colour terms in other Germanic languages (such as Old Norse apalgrár, German apfelgrau, and Dutch appelgrauw) that are surely too strong to be coincidental.

They all mean literally ‘applegrey’. Add to this such forms as French grispommelé, again literally ‘applegrey’, and Russian yablokakh ‘dappled’, a derivative of yábloko ‘apple’, and the inference becomes even more compelling – that dappled is related in some way as yet unexplained to apple. Many of the above terms were applied specifically to grey horses marked with round blotches, and so perhaps the word had its beginnings in a perceived resemblance in shape between such markings and apples.

incline: incline: [13] Latin -clīnāre (a relative of English lean, but itself only ever recorded in compounds) meant ‘bend, lean’. Add to this the prefix in- and you had inclīnāre ‘lean towards’. This was originally borrowed into English via Old French encliner as encline – a form which survived until the 17th century, when the latinized incline began to take over. The metaphorical use of the word to indicate a person’s disposition or preference dates back to Roman times.

cater (v.): "provide food for," c. 1600, from Middle English catour (n.) "buyer of provisions" (c. 1400; late 13c. as a surname), a shortening of Anglo-French achatour "buyer" (Old North French acatour, Old French achatour, 13c., Modern French acheteur), from Old French achater "to buy," originally "to buy provisions," perhaps from Vulgar Latin *accaptare, from Latin ad- "to" + captare "to take, hold," frequentative of capere "to take" (see capable).
