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.
