In Gbaya, the notion of “pools” in Psalm 84:6 is emphasized with luŋgum, an ideophone used to describe the accumulation of water.

The previous aridity of the valley of Baca is emphasized with kútú-kútú, an ideophone that refers to a head covered with scabs, a crusty head, or something scaly.

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