1st person singular optative (potential) of abhibhavati; or more likely, non-finite form in locative absolute construction, resolved as abhibhūsiṁ (imperfect/past tense)
Analysis. abhi + bhavati: 'to bear down on (abhi-) becoming/being (-bhavati)', hence to overcome or master by bearing down upon. May also contain bhū- 'to be/become' with the sense of overwhelming or towering over.
Etymology. abhi- 'toward and over, bearing down' (Latin ob-, English be-) + bhavati 'becomes, is' (Indo-European *bheuh-, English be, German Buße). The prefix carries its concrete spatial sense of approaching and overwhelming into the meaning of mastery and suppression.
