gas

I. gas, n.1
    (gæs)
    Pl. gases (ˈgæsɪz). Forms: 7–8 gass, 8–9 gaz, 7– gas.
    [A word invented by the Dutch chemist, J. B. Van Helmont (1577–1644), but avowedly based upon the Gr. χάος (‘halitum illum Gas vocavi, non longe a Chao veterum secretum.’ Ortus Medicinæ, ed. 1652, p. 59 a); the Dutch pronunciation of g as a spirant accounts for its being employed to represent Gr. χ; perh. suggested by Paracelsus's use of chaos for the proper element of spirits such as gnomes: see gnome2.
    Van Helmont's statement having been overlooked, it has been very commonly supposed that he modelled his word on Du. geest spirit, an idea found at least as early as 1775 (Priestley On Air Introd. 3). Van H. also invented the term blas, which has not survived, while gas has been adopted (usually in the same form) in most European languages; the spelling in F. and Pg. is gaz, which was also employed by English writers for a time.]
     1. An occult principle supposed by Van Helmont to be contained in all bodies, and regarded by him as an ultra-rarefied condition of water (see quot. 1662). Obs.

1658 R. Franck North. Mem. (1694) 202 Insomuch, that neither Gass nor Blass, nor any nauseating suffocating Fumes, nor hardly Death it self can snatch them from Scotland. 1662 J. Chandler Van Helmont's Oriat. 69 Because the water which is brought into a vapour by cold, is of another condition, than a vapour raised by heat: therefore..for want of a name, I have called that vapour, Gas, being not far severed from the Chaos of the Auntients..Gas is a far more subtile or fine thing than a vapour, mist, or distilled Oylinesses, although as yet, it be many times thicker than Air. But Gas it self, materially taken, is water as yet masked with the Ferment of composed Bodies. 1692 tr. Blancard's Phys. Dict. (1693) 99/2 Gas, a term used by Helmont, and signifies a Spirit that will not coagulate, or the Spirit of Life, a Balsom preserving the Body from Corruption. 1743 Lond. & Country Brew. ii. (ed. 2) 154 Your Water never is to boil; for Boiling irritates and evaporates the subtile, fine, penetrating Gas or Spirit.

    2. Any aeriform or completely elastic fluid; matter in the condition of an aeriform fluid. Usually applied only to those elastic fluids which remain such at ordinary atmospheric temperatures; the gaseous forms of substances ordinarily found solid or liquid being by preference called vapours.
