Suppose someone is using the word "apology" in the theological sense, i.e., a "defense". I'm inclined to use the word "apologia" because it immediately distinguishes it from the typical meaning of "apology", but I'm wondering if this is considered correct:
"In Dr. Salien's apologia of Quebec French..."
or is this better:
"In Dr. Salien's apology for Quebec French..."
You see the problem - Dr. Salien is defending Quebec French, not saying that he is sorry for it.
