The basic grammatical unit recognized at this time was the morpheme, though many linguists did not use the term itself. Language was thought to be (among other things perhaps) a repertory of morphemes. A sentence consisted of a sequence of morphemes.

A word, like a sentence, was a sequence of one or more morphemes, but the processes by which morphemes combined to form words were different from those by which sentences were formed. Within the word at least two types of morphemes could be distinguished, often called roots and affixes.
