Etymology 1
The function of this preposition was previously done with the use of sē, sēd (see sē-, sed), from Proto-Indo-European *swé (“self”), thus meaning "by itself", "without". Some still refer the si- in sine to this root, others refer it to Proto-Indo-European *só (“this”), whence si (“if”). And as sometimes nesi was also written, with -ne being nē (“not”), sine might literally mean "not this". Compare with nisi.
Others yet refer sine to Proto-Indo-European *seni (“for oneself, without”), itself maybe related to *swé. Thus cognate with Ancient Greek ἄτερ (áter, “without”), Old English sundor.
Preposition

- (with ablative) without
