poor: [13] Poor came via Old French povre from Latin pauper ‘poor’. This is thought originally to have been a compound meaning literally ‘getting little’, formed from paucus ‘little’ (a distant relative of English few) and parāre ‘get, prepare’ (source of English prepare). Its derivative paupertās has given English poverty [12], and pauper itself was acquired by English in the 16th century as a noun meaning ‘poor person’.
