Ring very loudly in departing (3)
I believe the answer is:
off
'departing' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'ring very loudly' is the wordplay.
'ring' becomes 'O' (letter resembling a ring).
'very loudly' becomes 'ff' (short for fortissimo, 'very loud' in music).
'o'+'ff'='OFF'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for off that I've seen before include "Far from fresh" , "Away, or no longer on the menu perhaps" , "Discontinued" , "Away, or beginning to decay" , "Rotten" .)
