The following is a list of Welsh Place Names that have been featured in Auntie’s Travels.
Aber: Can have a number of meanings based upon its geographical position. Often refers to the mouth or estuary of a river, but can also mean a small river or a confluence of two rivers.
Aberafan: refers to the Afon (River) Afan. The origin of Afon is uncertain, and may be very old, dating to the original Breton language spoken in Briton.

Another suggestion is that it is from “A-Ban” meaning “from the heights” due to its comparatively quick descent from hills to the sea.
