For example, to pronounce two vowels as one sound is
not neither profitable nor damaging.
The Neogrammarians’ basic axiom is that sound change
is regular, without exceptions; about how sound changes, they say that it is
not sudden but so slow and so slight and not noticed by speakers.
The Neogrammarians tend to separate de language from
their speakers, so it seems sound change be independent of them.
For Milroy it is the opposite, this aspect of
sociolinguistic has necessarily to deal with speakers.
With regard to the speech sounds, Milroy says that
they do not change but in the course of time one sound is substituted by
another.
The change of the sounds is principally a process by
which speakers change their language and for this reason Milroy disagrees with the
Neogrammarians’ idea of “blind” sound change.
Lexical diffusion is a socially gradual process and
abrupt replacement pattern, by which a form changes and the resulting form is
markedly different to the original one.
