Etymologies

Latin, from Greek, liquid bitumen, of Semitic origin; see npṭ in Semitic roots.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From Latin naphtha, from Ancient Greek νάφθα (náphtha), ultimately from Old Persian 𐎴𐎳𐎫 (naft). The Greek mediation is reflected in the spelling – ‘ph’ and ‘th’ (from ‘φ’ and ‘θ’). (Wiktionary)
