It’s very wet in southeast central Spain (3)
I believe the answer is:
sea
'it's very wet' is the definition.
I can't judge whether this definition defines the answer.
'southeast central spain' is the wordplay.
'southeast' becomes 'se' ('SE' can be a synonym of 'southeast').
'central' says to take the centre.
The middle of 'spain' is 'a'.
'se'+'a'='SEA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for sea that I've seen before include "Cause of flooding" , "Large body of salt water" , "Watery expanse" , "Vast expanse" , "Cod's home?" .)
