Hastily and tearfully boy gives up space for man (5)
I believe the answer is:
madly
'hastily' is the definition.
(thesaurus)
'for man' is the wordplay.
'for' becomes 'mad' (I am not sure about this - if you are sure you should believe this answer much more).
'man' becomes 'ly'.
'mad'+'ly'='MADLY'
'and tearfully boy gives up space' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for madly that I've seen is " "Deeply truly ____"".)
