Hengoed

Morphology: hen+coed
Phonetic: hen-goyd

The name literally means "old wood". The village is named after Hengoed Hall, a large house in the area though interestingly, maps from 1886 show that Hengoed Hall was to the north of the settlement of Cefn Hengoed whereas by today, Cefn Hengoed lies above and to the north of modern-day Hengoed.
