Welsh toponyms were used to describe the area before a village was built there in the early 19th century. Around 1570, the area was known as Aber Pennarthe; by 1600, it was known as Aberpennarth; and by 1638, it was known as Tir Aber Penarth (which translates to “Mouth of the river Pennar”). Another toponym, Dyffryn (Valley or plain between hills), seems to have gained significance around the turn of the 18th century. The home of the Bruce family was first known as Aberpennar, but by 1691 it was being referred to as Aberpennar alias Dyffryn, and by 1717 it was being referred to as Dyffrin alias Aberpennar. When it was renovated in the middle of the 18th century, it was simply known as Duffryn. Even though the river’s mouth is close by, the early village is called Dyffryn on tithe maps from the time period.

The Mountain Ash Inn, located on the historic Aberdare Road, is the inspiration for the town’s English moniker. It was opened in 1809. According to Thomas Morgan, the land was leased by the owner, John Bruce Pryce, to a man named David John Rhys, who subsequently constructed a public house on the plot. Rhys gave Pryce the name “Cerdinen” for the new structure because he saw a solitary “Cerdinen” (the Welsh term for a mountain ash tree, sometimes known as a rowan) nearby.
