Important recorded forms include νύξ (Ancient Greek) and ἡμέρα (Ancient Greek). Morphologically, the ending or combining element turns the older base into the present English part of speech. The modern sense follows that older lexical line closely. In current use it covers relating to a full period of a day and a night (24 hours).
