Morphology

mastoid = mast + oid

Formed from the combining form 'mast-' (meaning 'breast') + suffix '-oid'; the combining form is not a standalone English word and the anatomical meaning is technical, so learners cannot derive the sense from common English 'mast'.

Etymology

Mastoid comes from the Greek root masto- meaning 'breast' and the ending -oid meaning 'like'. So mastoid literally means 'breast-shaped', which helps you remember it describes something with the rounded shape behind the ear.
