"to call or summon forth or out," 1620s, from French évoquer or directly from Latin evocare "call out, rouse, summon," from assimilated form of ex "out" (see ex-) + vocare "to call," which is related to vox (genitive vocis) "voice" (from PIE root *wekw- "to speak"). Often more or less with a sense of "calling spirits," or being called by them. Of feelings, memories, etc., by 1856. Related: Evoked; evokes; evoking.
