inobon

English: Translation
To have been left behind; patient-focused perfective, profiling the person or object that was not taken along: something or someone was deliberately or contextually left behind.
Notes

inobon (-in- + obon)

This is patient-focused perfective or completed:

Intentionality is likely supplied by context, rather than encoded by -in- alone. The central grammatical distinction is that the entity left behind is profiled as the affected patient.
