manner vs custom

Hi everyone!

what’s the difference? when do i use custom and/or manner?

thanks!

Manner is the way of behaving or acting and the way something happens or is done: he answered in an easy manner.

In the plural it’s the way of acting in public: table manners; bad manners; it is bad manners to put your knife in your mouth.

Custom can have the sense of ‘habit’ or ‘usual activity’: we had supper very late, as is our custom.

Another definition of ‘custom’ is ‘tradition’: it’s the custom in that country to marry the children off before they are six years old.
