- 1義務性的、必須的（也常帶點調侃意味，指「照慣例一定會有」的東西）
Something that is required - you have to do it, it's not a choice. It's a slightly formal word: you might call a school uniform 'obligatory,' or describe a boring but required part of a ceremony as 'the obligatory speech.' It's often used a little jokingly, when something is so predictable it feels like a rule, like 'the obligatory group photo' at the end of a trip.

組成From Latin ob- (toward) + lig (to tie/bind) - the idea is that a rule 'ties' you to doing something.
