Morphology
coumarin = coumar + in
The form comes from a borrowed plant name and the element 'coumar' is not a recognizable English base; '-in' only marks a chemical substance, so learners cannot derive the meaning from the parts.
Etymology
Coumarin comes from the French name coumarou for the tonka bean, a South American seed known for its 'sweet smell'. Because chemists first found this scent in the tonka bean, coumarin became the name of a fragrant chemical used in perfumes, flavorings and some medicines.
