A child’s accent is decided by those around them at playgroup and nursery, not at school or home, a study suggests.
I don’t doubt at all that an accent is determined by such things. My complaint is the idea that a child only has one accent.
Simply not true (OK, not true in my experience). As with young children finding it easy to learn two languages, so having more than one accent is entirely possible. And I would argue entirely likely, when there are one or more accents in a child’s life. A home one and a school one for example.
Certainly was true of me. When at primary in Bath, good strong Bathonian. And the standard Eng middle class at home, like what I speak now. Of we move to Italy to the Forces school when I’m 8. My mother still remarks on the near cockney (probably closer to what we would call estuarine now) that my brother and I both picked up in weeks. And started speaking as we walked through the doors of the school and dropped the moment we left them.
We know very well that children are incredibly adaptable linguistically. Why anyone at all would think this wasn’t true of accents I don’t know.
