• John A. Simpson and Edmund S. C. Weiner, editors (1989), “crepusculum”, in The Oxford English Dictionary, 2nd edition, Oxford: Clarendon Press, →ISBN.

Uncertain; possibly from *crepus, *crepes, or *crepos combined with the suffix -culus. One possibility holds that this originates in a Proto-Indo-European form *ksep, that became *ksep-os or *ksep-əs-, then *ksep-os before emerging as *crepus. This sound could be explained through the dissimilation of the initial *s or through a shift from *ks- to *kr-. Varro suggests the term derives from creper, which was itself borrowed from Sabine.

   • 116 BCE – 27 BCE, Marcus Terentius Varro, De Lingua Latina 6.5:

     Secundum hoc dicitur crepusculum a crepero: id vocabulum sumpserunt a Sabinis, unde veniunt Crepusci nominati Amiterno, qui eo tempore erant nati, ut Lucii prima luce in Reatino; crepusculum significat dubium; ab eo res dictae dubiae creperae, quod crepusculum dies etiam nunc sit an iam nox multis dubium.

     (please add an English translation of this quotation)

In Medieval use (e.g., Bede), sometimes conceived as a particular period of evening lasting from sunset to vespers, the darker period of twilight when Venus and the stars began to appear.
