In Gbaya, the notion of «ravaging» (or «make waste») in Psalm 80:13 is emphasized with lɔkɔti-lɔkɔti, an ideophone used to describe complete destruction, devastation.
Ideophones are a class of sound symbolic words expressing human sensation that are used as literary devices in many African languages. (Source: Philip Noss)
