puny: [16] Etymologically, puny means ‘born later’. It was borrowed from Old French puisne, a compound adjective formed from puis ‘afterwards’ and ne ‘born’ (a relative of English native, nature, etc). This signified ‘junior’, in which sense it was originally acquired by English as puisne. This spelling survives (albeit pronounced the same as puny) as a term denoting a judge of junior rank, and the anglicized orthography has since the 18th century been reserved to ‘feeble, small’.
