German terribly fit for the present (4)
I believe the answer is:
gift
'the present' is the definition.
(I've seen this before)
'german terribly fit' is the wordplay.
'german' becomes 'g' (abbreviation).
'terribly' indicates an anagram.
'fit' with letters rearranged gives 'ift'.
'g'+'ift'='GIFT'
'for' acts as a link.
(Other definitions for gift that I've seen before include "Offering" , "Present or special talent" , "Endowment" , "A natural attribute" , "[BOUNTY] ?" .)
