Mediterranean port provided answer after show of surprise (5)
I believe the answer is:
haifa
'mediterranean port' is the definition.
(I've seen this in another clue)
'provided answer after show of surprise' is the wordplay.
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'answer' becomes 'a' (abbreviation eg in Q and A).
'after' says to put letters next to each other.
'show of surprise' becomes 'ha' (I can't explain this - if you can you should believe this answer much more).
'if'+'a'='ifa'
'ifa' after 'ha' is 'HAIFA'.
Can you help me to learn more?
(Other definitions for haifa that I've seen before include "Chief port of Israel" , "Israel's main port" , "Middle East city" , "Major Israeli port" , "Major port in northwestern Israel" .)
