One who enkindles; something that ignites or inspires; an igniter.
From 'enkindle' plus the agent suffix '-er' (one who does the action). This follows the standard English pattern of creating agent nouns from verbs.
Medieval and Renaissance writers used 'enkindler' to describe muses, lovers, and great leaders as 'enkindlers of virtue or passion'—it's a much more literary way of saying 'someone who inspires' that captures both fire and emotion.
