Starting off virtual Zoom ceremony? (6)
I believe the answer is:
ritual
'ceremony?' is the definition.
(I've seen this in other clues)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ritual that I've seen before include "Habit, routine" , "Ceremony, regular procedure" , "Series of actions used in religious ceremony" , "Ceremony following a prescribed order" , "Ceremony or protocol" .)
