Post by Markus AppelI'm particularly looking for slight nuances in usage, that's the point.
Are they EXACTLY the same or not?
OED2 treats the two words with independent entries, without mentioning
either as a synonym of the other. I'm inclined to argue we have here
a distinction without a difference.
[Excerpts from the two entries:]
"derogative, adj."
Characterized by derogating; tending to derogation.
1477 in Eng. Gilds (1870) 305 Prejudiciall or derogatyve to the
liberties..of the bisshop. ...1888 Cornhill Mag. Jan. 73 Too
derogative of the intelligence of Londoners.
"derogatory, adj."
1. Having the character of derogating, of taking away or detracting
from authority, rights, or standing, of impairing in force or effect.
Const. to, from (of).

was annulled as derogatory to the King's just rights.
2. Having the effect of lowering in honour or estimation; depreciatory,
disparaging, disrespectful, lowering.
