Brit.

/ˈpʌɪrənɔɪd/, U.S.

/ˈpaɪrəˌnɔɪd/

Origin: A borrowing from Latin; modelled on a German lexical item. Etymon: Latin pyrenoides.

Etymology: < post-classical Latin pyrenoides (1690 in the passage translated in quot. 1693 at sense A.) < Hellenistic Greek πυρηνοειδής shaped like a fruit-stone < ancient Greek πυρήν fruit-stone (see pyrene n.¹) + -οειδής -oid suffix. In use as noun after German Pyrenoid (F. Schmitz 1883, in Verhandl. des Naturhistorischen Vereins der Preussischen Rheinlande u. Westfalens 10 37).

†A. adj.

Resembling in form the stone of a fruit. Obsolete. rare.Apparently only attested in dictionaries or glossaries.
