Pretenders and Dabblers
This small set of 21 obscure words consists of nouns used to define minor, inferior, or petty members of various professions. The words end with '-aster', a Latin pejorative suffix indicating incomplete resemblance or lesser status. These words are little used today, but in another age were devices of scorn used by the intelligentsia to deride their lesser fellows. With a little creativity, practically any name for a profession can be altered in this way, should you find a desirable object for your contempt.
