Morphology

collagen = colla + gen

Formed from specialized combining elements ('colla-' + '-gen') that are not recognizable English base words to an average B1 learner, so the meaning cannot be reliably derived from common vocabulary.

Etymology

Collagen comes from the Greek root kolla meaning 'glue' and -gen meaning 'to make', the same -gen you see in generate. So, collagen is like the body's natural glue that holds skin, bone, cartilage and tendons together.
