Struggle to change a gift, being out of breath! (5)
I believe the answer is:
fight
'struggle' is the definition.
(I know that struggle can be written as fight)
'change a gift being out of breath' is the wordplay.
'change' indicates an anagram.
'being out of' means to remove the last letter (I've seen 'out' mean this).
'breath' becomes 'ht' (I am not sure about this - if you are sure you should believe this answer much more).
'gift' with its last letter taken away is 'gif'.
'gif' anagrammed gives 'fig'.
'fig'+'ht'='FIGHT'
'to' is the link.
Can you help me to learn more?
(Other definitions for fight that I've seen before include "Struggle; quarrel" , "Come to blows" , "Strive - struggle" , "Campaign against - quarrel" , "Brawl; argue" .)
