• sulpur (archaic)
• sulfur (late-Classical)

From a Hellenisation of earlier sulpur, from the root *selp- (“fat, oil”). Cognate with English salve, Sanskrit सर्पिस् (sarpís, “cleaned melted butter”), सृप्र (sṛprá, “greasy, smooth”), Tocharian B ṣalype (“ointment”), and perhaps ἔλπος (élpos, “?olive oil, fat”) or Ancient Greek ὄλπη (ólpē, “flask for oil”).

According to De Vaan citing Szemerényi,[1] perhaps from an s-stem Proto-Indo-European *sélpos. However, De Vaan finds both the -él- > -ól- and -os > -ur changes to be irregular (for -ol- > -ul- see sulcus), adding that perhaps it comes from Proto-Italic *solpor, from an r/n-stem Proto-Indo-European *sólpr̥ instead.

• (Classical) IPA^(key): /ˈsul.pʰur/, [ˈs̠ʊɫ̪pʰʊr]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈsul.fur/, [ˈsulfur]
