Squeezing hard, give relative a cuddle before beginning on tennis player (4)
'beginning on tennis player' is the definition.
'hugh grant' can be an answer for 'player' (British actor). I'm not certain of the 'beginning on tennis' bit.
'squeezing hard give relative a cuddle before' is the wordplay.
'squeezing' is an insertion indicator (squeeze can mean hug or embrace).
'hard' becomes 'h'.
'give relative' becomes 'grant' (I can't explain this - if you can you should believe this answer much more).
'a cuddle' becomes 'hug' (I've seen this before).
'before' says to put letters next to each other.
'grant' after 'hug' is 'huggrant'.
'h' going inside 'huggrant' is 'HUGH GRANT'.
Can you help me to learn more?
'squeezing hard give relative a' is the definition.
I can't judge whether this definition defines the answer.
'cuddle before beginning on tennis player' is the wordplay.
'cuddle' becomes 'hug' (I've seen this before).
'before beginning on tennis player' becomes 'h' (I can't explain this - if you can you should believe this answer much more).
'hug'+'h'='HUGH'
(Other definitions for hugh that I've seen before include "Middle name of WH Auden" , "W.H. Auden's middle name" , "man!" , "- Grant, British actor" .)
