This is not my business... and poking my nose into your conversation, but "explicate" and "explication" they do exist, and they come from Latin as we know.
To explicate means to unfold something, i.e. to explicate a poem. I've found these links amongst others which can provides us some "explanations".
Sometimes "to explicate" goes along with its opposite meaning "to implicate"... if I'm not mistaken.
