Oriental bird on stormy sea (7)
I believe the answer is:
eastern
'oriental' is the definition.
(similar in meaning)
'bird on stormy sea' is the wordplay.
'bird' becomes 'tern' (tern is a kind of bird).
'on' says to put letters next to each other.
'stormy' indicates an anagram (stormy suggests disruption).
'sea' with letters rearranged gives 'eas'.
'tern' put after 'eas' is 'EASTERN'.
(Other definitions for eastern that I've seen before include "Coming from the Orient" , "Of the direction of the rising sun" , "from afar" , "Chinese', for example" , "Facing away from the west" .)
