River Teifi
river in Wales, UK
The River Teifi (Welsh: Afon Teifi) is a river in Wales. It forms the boundary for most of its length between the Welsh counties of Ceredigion and Carmarthenshire, and for the final 3 miles (4.8 km) of its total length of 76 miles (122 km), the boundary between Ceredigion and Pembrokeshire. Its estuary is northwest of Cardigan, whose Welsh name is Aberteifi, meaning 'mouth of the Teifi'.
Geography
The source of the River Teifi is the Llyn Teifi, the second-largest of the five Teifi lakes (Welsh: Llynnoedd Teifi) after Llyn Egnant located in Elenydd. It is situated towards the north of the county of Ceredigion in Elenydd at 1,493 feet (455 m). The river flows past Strata Florida Abbey and then through Pontrhydfendigaid before turning broadly southwest. Here it passes through Cors Caron, an extensive peat morass also known as Cors Goch Glanteifi (translated from Welsh as red bog on the banks of the Teifi). From here the river descends through pastures and bogs forming meanders on farmland below. Several small tributaries join from the valley with gorges, rocky and tree-lined sections also in the area.
Over the next 30 miles (48 km), the Teifi meanders southwest in a gentle arc passing through Tregaron, Llanddewi Brefi, Cwmann, Lampeter, Llanybydder, Llandysul, Newcastle Emlyn, and Cenarth.

Why this record matters
A short description can identify a subject without explaining its stakes. For “River Teifi”, the useful work is to connect “river in Wales, UK” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q1523834. VIAF identifies the subject as 315530474. Authority coordinates are 52.083, -4.667. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
