Jewish Babylonian Aramaic

pāšōr - lukewarm, lukewarm water (DJBA 941)

PS
*pšr - to tear loose, to melt (EDA I 452)
The meanings “to interpret, to explain”, broadly attested for this root throughout WS, must be due to Akkadian influence (Wagner 1966, 96), either immediately or with various intermediaries (Akkadian > Aramaic > Arabic > MSA)
