Chap touring Spain gets tight (4)
I believe the answer is:
mean
'tight' is the definition.
('mean' can be a synonym of 'tight')
'chap touring spain' is the wordplay.
'chap' becomes 'man' (I've seen this before**).
'touring' means one lot of letters goes inside another (touring can mean going round).
'spain' becomes 'e' (abbreviation for Espana).
'man' going around 'e' is 'MEAN'.
'gets' acts as a link.
(Other definitions for mean that I've seen before include "very good" , "Represent - average" , "Import" , "Bad-tempered" , "Niggardly" .)
