In Spain, little point in one's getting hungry (5)
I believe the answer is:
empty
'hungry' is the definition.
(similar in meaning)
'in spain little point in one's' is the wordplay.
'in spain little' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'point' becomes 'pt' (abbreviation for point).
'in' is an insertion indicator.
'one's' becomes 'my' (both can mean belonging to the person writing).
'pt' placed into 'my' is 'mpty'.
'e'+'mpty'='EMPTY'
'getting' is the link.
Can you help me to learn more?
(Other definitions for empty that I've seen before include "Dead man" , "Devoid of content" , "(Of words) lacking sincerity" , "Like the sherry decanter by the time gran's jolly" , "Unfilled" .)
