Furoln.adj.

Brit.

/ˈfjʊərɒl/, U.S.

/ˈfjʊrɑl/

Forms: also with lower-case initial.

Origin: Formed within English, by compounding. Etymons: fuel n., road oil n. at road n. Compounds 6.

Etymology: < fu- (in fuel n.) + -rol (representing road oil n. at road n. Compounds 6, and perhaps also echoing -ol suffix).The term was apparently first suggested by W. F. Parish in 1920 (see quot. 1921).

Used attributively with reference to a modified form of the Saybolt viscometer (see Saybolt n. 2) with a large orifice, for use with oils of high viscosity. Also as adj. (as postmodifier).With Furol second (and second Furol) cf. Saybolt second n. at Saybolt n. 3.
