Moving into stormily sea-girt land (7)
I believe the answer is:
estonia
'land' is the definition.
(Estonia is a country)
'moving into stormily sea-girt' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'into' is 'toni' which is located in the answer.
an anagram of 'sea' is 'esa' which is located in the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for estonia that I've seen before include "So eat in about here in Northern Europe" , "European republic, became independent again in 1991" , "Nation" , "Land" , "One of the Baltic States" .)
