olibanum

Borrowed from Medieval Latin olibanum, from Latin oleum libani, the first word meaning oil and the second from Ancient Greek λίβανος (líbanos, “frankincense (Boswellia sacra)”), from a Semitic source. See the Semitic root L-B-N لبن, meaning "white". Cognate with Biblical Hebrew לְבוֹנָה (l'voná, “frankincense”), Arabic لبان (lubān, “frankincense”). (Compare benzoin for a similar process of metanalysis.) Doublet of oliban.
