arcane [arcane 词源字典]: arcane: [16] Arcane comes from the Latin adjective arcānus ‘hidden, secret’. This was formed from the verb arcēre ‘close up’, which in turn came from arca ‘chest, box’ (source of English ark). The neuter form of the adjective, arcānum, was used to form a noun, usually used in the plural, arcāna ‘mysterious secrets’.
=> ark[arcane etymology, arcane origin, 英语词源]
ark: ark: [OE] The notion underlying ark seems to be that of ‘enclosing or defending a space’. Its ultimate Latin source, arca ‘large box or chest’, was related to arx ‘citadel’ and to arcēre ‘close up’ (from which English gets arcane). Arca was borrowed into prehistoric Germanic, and came into English as ærc. In addition to meaning ‘chest’ (a sense which had largely died out by the 18th century), it signified the ‘coffer in which the ancient Hebrews kept the tablets of the Ten Commandments’ – the Ark of the Covenant – and by extension, the large commodious vessel in which Noah escaped the Flood.
