derivation morphemes , i.
e. those which serve to build words, we are only interested in them in so far as
they are grammatically relevant, and that is the case if they show that the
word belongs to a certain part of speech, and if they serve to distinguish one part of
speech from another. This grammatical significance of derivation morphemes, if it
is there at all, is always combined with their lexical meaning. For instance, if
we take this pair of words:
write v. and
writer n., the derivative morpheme
-er has a grammatical significance, as it serves to distinguish a noun from a verb,
and it has its lexical meaning, as the lexical meaning of the noun
writer is
different from that of the verb
write.
