field: [OE] Like plain, field seems originally to have meant ‘area of flat, open land’. It comes ultimately from the Indo-European base *plth-, which also produced Greek platús ‘broad’, English place and plaice, and possibly also English flan and flat. A noun derived from it, *peltus, entered prehistoric West Germanic as *felthuz, which subsequently disseminated as German feld, Dutch veld (English acquired veld or veldt [19] via its Afrikaans offshoot), and English field.
=> flan, flat, place, plaice, veld
