|A. deŋi=A=O||A scratch, dig O|
|B. kaŋŋi=A=O||A pierce, poke O|
Deŋi can be seen as a more intense form of kugi, as it involves touching with some force. Kaŋŋi would be even more intense. The etymologies of both these verbs are unknown. Kaŋŋi is used sometimes used with other verbs to add a sense of puncturing, as in:
|C. dello-kaŋŋi=S||S sprout (piercing the soil)|
|D. kuppe-kaŋŋi=A=O||A throw O through something, piercing it|
|E. kaŋŋi-kaŋŋi=A=O||A kill O (by stabbing or cutting)|
Reduplicated deŋi-deŋi=S is the standard, polite way to describe sexual activity. It is intransitive, usually with a plural subject. With a singular subject, a companion an be added with the peripheral phrase marker ne. The other sexual verbs, kugi-kugi=S (referencing manual stimulation), kaŋŋi-deŋi=A=O (A penetrates O), and kaŋŋi-kuno=S (S is penetrated), are not polite and should not be used with people one doesn’t know.
And that’s it. That’s all 38 verbs in Xunumi-Wudu.
