simultaneousadj.

/sɪməlˈteɪnɪəs/

Etymology: < Latin type *simultāneus, formed (probably after mōmentāneus) on Latin simul at the same time: compare French simultané (1740), Spanish simultaneo, Portuguese simultaneo, Italian simultaneo. Medieval Latin simultāneus is given by Du Cange only in the sense of ‘simulated’. Blount ( Glossogr. 1656), citing simultaneous from L'Estrange, wrongly associates it with Latin simultas, and explains it as ‘that is privily displeased or hates with dissembling countenance’. Phillips (1658), as usual, repeats the mistake in different words. Marvell in his Def. Howe (1678) refers to the word as ‘an elegant term of The Discourse's own production’ ( Wks., ed. Grosart, IV. 199).

a. Existing, happening, occurring, operating, etc., at the same time; coincident in time.
