The meaning “with” for the reflexes of PS *kV ‘like, as’ is not attested outside MSA. The original comparative meaning of *kV- left no trace in MSA. For the semantic shift from comparative to comitative cf. (with Bittner 1913a:8) Gez. məsla ‘with’ < məsl (*miṯl-) ‘likeness, similarity’ (CDG 365). (Kogan 2015:559)
