It's difficult to define a term so that everybody is satisfied. I think, to me, neutrality of an accent is more continuous than to you. You seem to say accents can be either neutral or not and there's nothing in between.
No, I've never said that accents can be neutral. I'm saying all accents are not neutral. I'm saying that there is no neutral way of saying 'o' as in 'dog', for example.
I, on the other hand, could say something is more neutral and something else is less. That's why I said Cockney was less neutral than
RP. Isn't it to you?
That's depends. How are you defining neutral?
I'm not going to try to strictly define what I mean by "neutrality"; it's too difficult.
Oh.
But I certainly think that a simple, absolute definition like yours makes the problem too simple.
It's not my definition. It's the definition of linguistics. If we were having a scientific discussion and you wanted to claim that a neutral pH is not 7, but the pH of the most numerous substances, I'd disagree there too. I'd also disagree if you said that the most neutral umpire was the one who gave the most equal number of points to the teams.
My definition, if I made one, would involve some kind of numerical representation of accents based on statistical data and then would say that
the neutral accent is that one which has the highest representation.
Well, then you're dealing with statistcs, and you'd be talking about the 'modal' accent. I would not disagree that a certain accent might be the one most represented, assuming we could agree on what makes two people's accents the same.
Of course,
what exactly I'd like to represent and
how I'd do that requires much thought. The existence and uniqueness of the highest representation should also be considered.
