Simple type but he shows skill in bridge (7)
I believe the answer is:
spartan
'simple' is the definition.
(I've seen this before)
'skill in bridge' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'in' indicates putting letters inside.
'bridge' becomes 'span' (synonyms).
'art' put inside 'span' is 'SPARTAN'.
'type but he shows' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for spartan that I've seen before include "Disciplined person" , "toughly-disciplined type" , "Lacking comfort or luxury" , "Ascetic - ancient Greek" , "Of conditions, harsh and lacking comforts" .)
