Throng involved in a primarily kind independent activity following sport (5-3)
I believe the answer is:
apres-ski
'activity following sport' is the definition.
I can't tell whether this definition defines the answer.
'throng involved in a primarily kind independent' is the wordplay.
'throng' becomes 'press' (I've seen this in another clue).
'involved in' indicates putting letters inside.
'primarily' suggests taking the first letters.
The initial letters of 'kind independent' is 'ki'.
'a'+'ki'='aki'
'press' going inside 'aki' is 'APRES-SKI'.
Can you help me to learn more?
(Other definitions for apres-ski that I've seen before include "Winter sports socialising" , "Evening activities in, say, Zermatt" , "Alpine resort party" , "Socialising after winter sport" , "Alpine jollities" .)
