Time one German given clubs (he's a golfer) (5,5)
I believe the answer is:
tiger woods
'a golfer' is the definition.
'time one german given clubs he's' is the wordplay.
'time' becomes 't' (abbreviation).
'one' becomes 'i' (Roman numeral).
'german' becomes 'ger' (abbreviation).
'given clubs he' becomes 'woods' (I can't explain this - if you can you should give a lot more credence to this answer).
't'+'i'+'ger'+'woods'='TIGER WOODS'
Can you help me to learn more?
(Another definition for tiger woods that I've seen is " Golfer - God swore it (anag)".)
