Bound to play this casual golfer taking old man round (8)
I believe the answer is:
leapfrog
'bound' is the definition.
(thesaurus)
'casual golfer taking old man round' is the wordplay.
'casual' is an anagram indicator (a casual or disordered version of the letters).
'taking' means one lot of letters goes inside another.
'old man' becomes 'pa' (both can mean someone's father).
'round' says the letters should be written backwards.
'pa' reversed gives 'ap'.
'golfer' anagrammed gives 'lefrog'.
'lefrog' placed around 'ap' is 'LEAPFROG'.
'to play this' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
