| Definition - The study and description of a language's morphemes.
As opposed to the older and more general term morphology, which is the "identification, analysis and description of the structure of morphemes and other units of meaning … like words, affixes, and intonation."
1. Those who study morphemics are called morphemicists.
Etymology - The word derives the term morpheme, which in turn derives from the Greek morphe, form or shape.
Oxford English Dictionary - Its first citation from 1947:
"Morphemics and tactics are both necessarily involved in grammar."
