allay: [OE] In Old English, alecgan meant literally ‘lay aside’ (-a ‘away, aside, out’, lecgan ‘lay’). The more recent senses ‘relieve, mitigate’ developed from the 13th to the 15th centuries owing to the influence of two formally similar Old French verbs: aleger ‘lighten’ (from Latin alleviāre, source of English alleviate [15]); and al(e)ier ‘qualify, moderate’ (source of English alloy). => lay[allay etymology, allay origin, 英语词源]
