Bed is large in ocean liner produced in the UK (8)
I believe the answer is:
scotland
'in the uk' is the definition.
('Scotland' is part of 'uk')
'bed is large in ocean liner' is the wordplay.
'bed' becomes 'cot' (cot is a kind of bed).
'is large' becomes 'l'.
'in' is an insertion indicator.
'ocean liner' becomes 'sand' (I can't explain this - if you can you should believe this answer much more).
'cot'+'l'='cotl'
'cotl' put inside 'sand' is 'SCOTLAND'.
'produced' acts as a link.
Can you help me to learn more?
(Other definitions for scotland that I've seen before include "Country of the UK" , "It is Alba in Gaelic" , "Land of clans and kilts" , "North of the border" , "The thistle is its emblem" .)
