pyrognomicadj.

Brit.

/ˌpʌɪrə(ʊ)ˈnɒmɪk/,

/ˌpʌɪrə(ʊ)ˈnəʊmɪk/, U.S.

/ˌpaɪroʊˈnɑmɪk/,

/ˌpaɪroʊˈnoʊmɪk/

Origin: A borrowing from Greek, combined with English elements; modelled on a German lexical item. Etymons: pyro- comb. form, Greek γνώμη , -ic suffix.

Etymology: < pyro- comb. form + ancient Greek γνώμη means of knowing, mark, token (see gnome n.¹) + -ic suffix, after German pyrognomisch ( T. Scheerer 1840, in Ann. d. Physik u. Chemie 51 495).

Mineralogy and Geology.

Of a mineral: becoming incandescent when heated, esp. to relatively low temperatures; of or relating to such behaviour.
