IPA: /ˈlæd.ən.əm/
KK: /lədˈænəm/
A sticky resin obtained from the leaves of certain shrubs, used in perfumes and incense.
The fragrance of the perfume was enhanced by the addition of ladanum.
Ladanum is derived from the Latin 'ladanum' (meaning a resin), which itself comes from the Greek 'ladanon' (meaning resin or gum). The word refers to a fragrant resin obtained from the cistus plant, used in perfumes and incense.
Think of the fragrant 'resin' ('ladanum') that comes from the cistus plant, which is why 'ladanum' refers to this aromatic substance.
