-logue
(lɒg)
the form assumed by the Gr. -λογος, -λογον in adapted words (most of them through Fr.), as analogue, catalogue, dialogue. The words with this ending which are designations of persons (in most instances repr. actual or assumed Gr. compounds of -λόγος ‘speaker, discourser’, and related to parallel formations in -logy) are now little used, derivatives in -loger, -logist, or -logian being commonly preferred. Examples are Assyriologue, † astrologue, ideologue, philologue, Sinologue, † theologue.
