Experienced deaconess caught out surprisingly (8)
I believe the answer is:
seasoned
'experienced' is the definition.
('seasoned' can be similar in meaning to 'experienced')
'deaconess caught out surprisingly' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'out' is a deletion indicator.
'surprisingly' indicates anagramming the letters.
'deaconess' with 'c' removed is 'deaoness'.
'deaoness' is an anagram of 'SEASONED'.
(Other definitions for seasoned that I've seen before include "Mature" , "Expert" , "Of food, flavoured with salt, pepper etc" , "Veteran - given added flavour" , "(Of wood) dried out for use as timber" .)
