Morphology

obligatory = obligate (semi-transparent) = oblig + atory

The transition from 'obligate' to 'obligatory' is clear, but the root 'oblig' may not be immediately recognized by learners.

Etymology

The word obligatory comes from Latin parts ob- 'to' and ligare 'to bind', the same idea behind the English verb oblige. So something obligatory 'binds' you to do it and is required by a rule or duty.
