Pronunciation

  • /ˈdeɪtaɪm/[1]

Etymology

It is a compound from English day + time.[2][3][4] The OED traces it to Old English dægtīma, which glosses Latin per diem (“by day”) in the Lambeth Psalter,[2][5] and compares Old Norse dagstími and Swedish dagtimme;[2] Etymonline and Dictionary.com instead date the English word to the 1530s.[3][4]

Earliest recorded meaning

The time between sunrise and sunset, when it is light: in Old English, in the Lambeth Psalter, where the sun shall not burn by day.[2][5]

Semantic evolution

The meaning has stayed the same since Old English.[2] Johnson (1755) defined it as the time of light, opposed to night, quoting Bacon.[6] The word is often used attributively, before another noun.[7]
