pileyoudaoicibaDictYouDict[pile 词源字典]
pile: English has three words pile. The commonest, ‘heap’ [15], originally meant ‘pillar’. It comes ultimately from Latin pīla ‘pillar’, source also of English pilaster, pillar, etc. This evolved in meaning to ‘pier or harbour wall made of stones’, and inspired a derived verb pīlāre ‘heap up’ (source of English compile [14]).

The sense ‘heap’ came to the fore in Old French pile, and passed into English. Pile ‘post driven into the ground’ [OE] was borrowed into Old English from Latin pīlum ‘javelin’. It was originally used for a ‘throwing spear’, ‘arrow’, or ‘spike’, and its present-day use did not emerge (via ‘pointed stake or post’) until the Middle English period. Pile ‘nap on cloth, carpets, etc’ [15] probably comes via Anglo-Norman pyle from Latin pilus ‘hair’ (which may be distantly related to English pillage and pluck, and lies behind English depilatory [17]).

tapestryyoudaoicibaDictYouDict
tapestry: [15] The ultimate source of tapestry is Greek tápēs ‘tapestry, woven carpet’. Its diminutive from tapētion was borrowed via late Latin tapētium into Old French as tapis ‘carpet’. From this was derived the verb tapisser ‘cover with a carpet’, and this in turn formed the basis of a noun tapisserie ‘carpets, woven material’. English took it over and altered it to tapestry.

1590s, "cloth having a velvet nap on one side," perhaps from Old English sceacga "rough matted hair or wool," from Proto-Germanic *skagjan (cognates: Old Norse skegg, Swedish skägg "beard"), perhaps related to Old High German scahho "promontory," Old Norse skagi "a cape, headland," with a connecting sense of "jutting out, projecting."
