Pharmacist - Apotheker
Librarian - Bibliothekar
So why the -ar ending? Is this a holdover from Greek or some strange anomaly? Are there other -thek endings that do this? I can think of one other: Diskothek, but I would imagine that one who frequents Diskos would be a Diskotheker, right?
Also, has anyone read The American Language by H.L. Mencken? Is it generally respected?
