Able to be called forth, summoned, or brought to mind; capable of being evoked.
From Latin 'evocare' (to call out, summon) + the English suffix '-able' (capable of being). The root 'vocare' means 'to call,' seen also in 'voice,' 'vocalize,' and 'invoke.' The meaning evolved from magical/religious summoning to any kind of mental or emotional calling-forth.
Medieval magicians believed certain spirits or demons were 'evocable'—they could be summoned with the right words or rituals. Now we use it for memories, emotions, or images that our minds can conjure up, showing how the word shifted from supernatural to psychological.
