Kedu n'ime ndi a bu nsupe?

Nsupe in Igbo refers to non-verbal communication - gestures, body movements, and physical signs used to convey messages without spoken words. It is an important aspect of Igbo communication studies.

Among the options given, ima aka (waving or beckoning with the hand) is a nsupe. It is a deliberate hand gesture used to communicate a specific message - such as calling someone to come closer, greeting from a distance, or signalling attention - without using words. The gesture carries a recognisable meaning that the receiver can interpret.

Ida mba (being discouraged/despairing) describes an emotional state rather than a deliberate communicative gesture. Ikpo okpo (knocking) is a physical action to announce one's presence, not a body-language gesture. Iku aka n'ukwu (hitting hand on foot) can be expressive but ima aka is the most widely recognised example of nsupe in Igbo communication studies.
