_Shipster_ (Vol. i., p. 339.).--That "ster" is a feminine termination
is the notion of Tyrwhitt in a note upon Hoppesteris in a passage of
Chaucer (_Knight's Tale_, l. 2019.); but to ignorant persons it seems
not very probable. "Maltster," surely, is not feminine, still less
"whipster;" "dempster," Scotch, is a judge. Sempstress has another
termination on purpose to make it feminine.
I wish we had a dictionary, like that of Hoogeven for Greek, arranging
words according to their terminations.
