    This may depend on the context. What is the one who explains things: a parent, teacher, priest, scientist, writer...? – Jan Jul 3 at 12:04
  • @jan I would say it about a consultant, or advisor. Definitely not a tutor, mentor or educator - thanks – TheHan Jul 3 at 13:37
  • @TheHan The problem with saying you want a word that applies to a consultant or an advisor but not to a tutor or mentor is that I can't think of any word that is so specific as that. For instance, if I say that somebody is an oracle ("a person giving wise or authoritative decisions or opinions"), anybody in any role could also be considered to be an oracle. Only role-type nouns will be specific, but they would likely be too specific. So, you're stuck with something too broad or something too narrow . . . – Jason Bassford Jul 3 at 15:48

The person you describe could be called an elucidator, meaning a person who has the ability to make something clear. An elucidator might, for example, put a problem into perspective, helping you to see it in a new light.

The etymology of elucidator:

Late Latin ēlūcidāre, ēlūcidāt- : Latin ē-, ex-, intensive pref.; see ex- + Latin lūcidus, bright (from lūcēre, to shine . . ..

Elucidator has cognates which include lucid, an adjective meaning clear; lucidity, a noun meaning the quality or attribute of being clear; and the verb elucidate, meaning to make clear. All four words carry with them the idea of light being brought to bear on something, making it clear and easily seen, hence understood. Here are sentences which include all four words:

Jill is a great elucidator, and unraveling a complex problem and making it lucid, is her gift. Lucidity is exactly what we need when we get "stuck" while trying to unravel the complexity ourselves, and Jill performs a critically important role in helping to elucidate and solve our problem.

  • wow - that elucidated my mind... thanks. – TheHan Jul 4 at 14:47
