From Middle English laves, lavas, lavage (“extravagant, wasteful, prodigal”), from lavas (“excessive abundance”), from Old French lavasse, lavache (“torrent of rain”); possibly later conflated in some senses by Middle English laven (“to pour out”), equivalent to lave + -ish. Compare Scots lawage, lavisch, lavish (“unrestrained, excessively prodigal, extravagant”). Compare also English lavy (“lavish, liberal”), Dutch lafenis (“lavishness”).
Typically precedes the noun it modifies; can also follow linking verbs like 'be' or 'seem'.
