Etymology

In summary

A learned borrowing from Latin salīva (“spittle”), replacing or merging with Middle English salive, salve (“saliva”), from the same Latin source. Further origin uncertain. Perhaps from Proto-Indo-European *salw-, *sal- (“dirt, dirty”), cognate with Old English salu (“dark, dusky”). More at sallow.
