Llawhaden, Pembrokeshire, also lies on a linguistic frontier of sorts. Re Thrapston: the tendency is for people living along the lower reaches of the River Nene, to pronounce the name "Neen"; along its upper reaches, "Nen" is favoured -- Thrapston is the approximate division-point. The south of Pembrokeshire was mostly settled many centuries ago, by non-Welsh folk: hence, English has since then been the area's main language. The north of the county remained Welsh, and for a long time, Welsh-speaking -- that still the case to some extent. The division runs along what students of the subject call the "Landsker Line"; on which Llawhaden is located.
