Smart padre works around pressure (6)
I believe the answer is:
dapper
'smart' is the definition.
(I've seen this in another clue)
'padre works around pressure' is the wordplay.
'works' is an anagram indicator (letters worked into a new form).
'around' is an insertion indicator.
'pressure' becomes 'p' (scientific abbreviation).
'padre' is an anagram of 'daper'.
'daper' enclosing 'p' is 'DAPPER'.
(Other definitions for dapper that I've seen before include "Neat, spruce" , "neat and smart in dress" , "Neatly turned out" , "Neat and well dressed" , "Stylish" .)
