Etymology

It is inherited from Middle English possybil, borrowed from Old French possible and directly borrowed from Latin possibilis (“that can be done”),[2][3] from posse (“to be able”) and the suffix -ibilis,[2][4] itself from potis (“able”) and esse (“to be”).[5] Barnhart notes that possibilis was coined by scholars in the 1st century AD to translate Greek δυνατός (dunatós, “possible”).[3] It is related to potent and possess.[3][6]

Earliest recorded meaning

That may be, that can exist or be done: probably between 1350 and 1375,[3] or the mid-14th century according to Etymonline.[2]

Semantic evolution

Possibility is from about 1385, in Chaucer,[3] and possibly from about 1400.[3] From 1488 to 1692 possible could mean “the greatest possible”,[7] and the sense “that may be true, conceivable” is recorded from 1582.[7] The noun, “that which may happen”, is from the 1640s.[2] The Century Dictionary insisted that possible means what may be, not what can be done, and that it should not be used for practicable.[2]
