单词 abietine
释义

abietinen.

Brit. /ˈabɪətiːn/, U.S. /ˈæbiəˌtin/
Forms: 1800s abietin, 1800s– abietine.
Origin: Partly a borrowing from French. Perhaps also partly a variant or alteration of another lexical item. Etymons: French abiétine ; abietene n.
Etymology: In sense 1 < French abiétine (A. Cailliot 1830, in Jrnl. de pharmacie 16 437) < classical Latin abiet- , abiēs fir tree (see abietic adj.) + French -ine -ine suffix5. Compare German Abietin (1834; < French). Sense 2 may show a spelling variant of abietene n. (compare sense 1 at that entry); it is unclear whether -ene comb. form or -ine suffix5 was the original suffix.
Chemistry.
