Etymology[edit]

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’).

Pronunciation[edit]

Noun[edit]

naphtha (countable and uncountable, plural naphthas)

  1. (dated) Naturally-occurring liquid petroleum.
  2. Any of a wide variety of aliphatic or aromatic liquid hydrocarbon mixtures distilled from petroleum or coal tar, especially as used in solvents or petrol.
    • 1918, W. B. Maxwell, chapter 7, The Mirror and the Lamp:
      The turmoil went on—no rest, no peace. […] It was nearly eleven o'clock now, and he strolled out again. In the little fair created by the costers' barrows the evening only seemed beginning; and the naphtha flares made one's eyes ache, the men's voices grated harshly, and the girls' faces saddened one.
    • 1995, Philip Pullman, Northern Lights:
      The Common Room and the Library were lit by anbaric light, but the Scholars preferred the older, softer naphtha lamps in the Retiring Room.
