In Gbaya, the notion of the dried up top of Carmel in Amos 1:2 is emphasized with ŋgaoo, an ideophone that refers to a reddish or brownish color like Sienna, like leaves scorched by fire or a charred object, or grass at the top of a hill that becomes dry.

Ideophones are a class of sound symbolic words expressing human sensation that are used as literary devices in many African languages. (Source: Philip Noss)
