Morphology
thyroglossal = thyro- + glossal (opaque) = thyro + glossal
Formed from specialized Greek combining forms used in medical terminology; the elements are not transparent to an average B1 learner.
Etymology
Thyroglossal combines the parts thyro- from thyroid, meaning 'neck gland', and glossal from glossa, meaning 'tongue', so it refers to the tube or connection between the thyroid and the tongue.
