पतिः समास‌ एव ONPANINI 14008

pati- पतिॱ is /ghi only in a compound.

So vanaspati- वनस्पतिॱ, prajApati- प्रजापतिॱ, bhUpati- भूपतिॱ are normal /ghi masculines, just like RSi- ऋषिॱ —

prajApataye प्रजापतये "to prajApati"
bhUpateH भूपतेः "of king"
vanaspati- वनस्पतिॱ m + /Gi → !**vanaspatau वनस्पतौ "on tree"

But the lone pati- पतिॱ m "lord, master, husband" is neither /ghi not /nadI —

patyau पत्यौ "in lord" by aut
patye पत्ये "to lord", unaffected by gherGiti
patyuH पत्युः "of lord" by khyatyAtparasya
