Sorry PHIL, but the old French and the Middle English beat you to that word. It is recorded as far back as 1340 according to the Oxford.
But I did find a signature phrase for our occasionally grumpy, but deeply sensitive honorary grammarian Dazza:
"It is no secret that the sensitive
grammarian
leads a deeply troubled life."
Yours to use Dazza, as you feel fit. Hope the beer's cold.
