Vulcan
Vulcan, from Latin Volcanus, has no accepted Latin or wider Indo-European derivation and is generally treated as a pre-Latin word, possibly of Etruscan background, naming one of Rome's oldest and most distinctly Italic gods.

Meaning
Volcanus, the Latin source of "Vulcan," sits alongside Neptune and Mars as one of the Roman divine names that plain Latin word-formation simply cannot explain. No convincing derivation from ordinary Latin vocabulary or from a reconstructable Proto-Indo-European root has won scholarly acceptance, and reference works on Latin etymology generally record the word's origin as obscure rather than offering a confident answer. The most commonly repeated proposal treats Volcanus as an Etruscan loanword, though this is asserted more often than it is demonstrated in detail, since Etruscan vocabulary is itself poorly documented and the specific Etruscan word that would stand behind Volcanus has not been identified with confidence. A further, more speculative comparison links the name to Cretan Greek Wélkhanos, a Cretan nature and underworld god whose own name is itself not securely Greek, raising the possibility of a shared pre-Greek Mediterranean source passed independently into both Crete and Italy rather than a direct borrowing in either direction. An isolated further comparison has been drawn to Sanskrit ulkā, "meteor" or "firebrand," though this remains a suggestive parallel rather than an established cognate relationship. What can be said with more confidence than the word's ultimate source is its antiquity within Roman religion itself: Vulcan is one of the oldest deities in the Roman pantheon, with a cult and a name that show no sign of being coined to translate the Greek smith-god Hephaestus, whom Vulcan was later identified with through interpretatio romana. The name's resistance to a clean Latin or Indo-European explanation is itself a kind of evidence, in the same way Mars's and Neptune's comparable obscurity is: Rome's very oldest religious vocabulary preserves words older than Latin's own recorded history, absorbed from whatever languages and peoples occupied Italy before Rome's earliest historical period, and Volcanus most likely belongs to that older, largely unrecoverable layer rather than to a coinage anyone can trace with real confidence.
What does the name Vulcan actually mean?
No one knows for certain. Latin Volcanus has no accepted derivation from ordinary Latin vocabulary or from a reconstructable Indo-European root, and standard etymological references treat the word's ultimate origin as obscure, most likely predating Latin itself rather than being a native Latin coinage.
Is Vulcan's name Etruscan?
It is the most commonly repeated proposal, but it is asserted more often than it is proven. Etruscan vocabulary is itself poorly documented, and no specific Etruscan word behind Volcanus has been identified with real confidence, so "probably pre-Latin, possibly Etruscan" is a more accurate summary than a confirmed Etruscan origin.
Why is Vulcan's name considered older than Rome's contact with Greek religion?
Because the name shows no sign of being built to translate Hephaestus, the Greek fire-god Vulcan was later identified with through interpretatio romana, and Vulcan's cult in Rome - including the ancient Vulcanal shrine at the foot of the Capitoline - is treated by Roman sources themselves as extremely old, consistent with a name inherited from Italy's pre-Roman past.

How does Vulcan's forge fit into his name and mythology?
The forge beneath a volcano, most famously Mount Etna in Roman and Greek poetic tradition, belongs to the mythology Vulcan inherited from Hephaestus through interpretatio romana rather than to the god's own name, which is unrelated in origin to any Latin word for fire or forging.
