Youngster accepting tip of lapel as component of suit (4)
I believe the answer is:
club
'component of suit' is the definition.
'club' can be an answer for 'suit' (playing card suit). I'm unsure of the 'component of' bit.
'youngster accepting tip of lapel' is the wordplay.
'youngster' becomes 'cub' (I've seen this in other clues).
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'tip of' suggests taking the first letters.
The initial letter of 'lapel' is 'l'.
'cub' enclosing 'l' is 'CLUB'.
'as' is the link.
Can you help me to learn more?
(Other definitions for club that I've seen before include "Dance venue" , "Golf implement" , "one of thirteen?" , "Stout stick, card suit and association" , "Weapon for an association" .)
