land: [OE] Land goes back to a prehistoric Germanic *landam. This seems originally to have meant ‘particular (enclosed) area’ (ancestor of the modern sense ‘nation’), but in due course it branched out to ‘solid surface of the earth in general’. The term is now common to all the Germanic languages, and it has distant relatives in Welsh llan ‘enclosure, church’ and Breton lann ‘heath’ (source of French lande ‘heath, moor’, from which English gets lawn). => lawn[land etymology, land origin, 英语词源]
