var. of -er 1 , usu. in nouns designating trades: collier; clothier; furrier; glazier.
[Middle English -ier(e), variant of -yer(e) (compare -yer)]


a noun suffix occurring mainly in loanwords from French, often similar in meaning to -eer, with which it is etymologically identical (brigadier; financier); it is also found in an older group of loanwords with stress on the initial syllable (barrier; courier) and in more recent borrowings without the final r sound (dossier; hotelier).
