genitive plural masculine of the present participle (sambhavesīnaṁ = sambhavatin + ānaṁ), meaning 'of those being possible' or 'of those that can arise'
Analysis. saṁ + bhavati: 'together' + 'becomes'; the prefix saṁ- combines with bhavati (become) to mean 'come together' hence 'arise, be possible'. The form shows the genitive plural of the present participle used attributively.
Etymology. √bhavati (become) is cognate with English 'be' and Sanskrit bhavati; the prefix saṁ- (together, with, completely) works like English 'same' and Latin con-, bringing elements into one unified state. The semantic shift from 'becomes together' to 'becomes possible' reflects how combined conditions allow something to arise.
