Holy place that may throb with intense activity (6)
I believe the answer is:
temple
'holy place' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for temple that I've seen before include "centre of interest?" , "Capital feature" , "child actress ..." , "Part of the forehead and place of worship" , "Delicate spot on the head" .)
