New Hampshire pair at Lord's visiting this country for free (6)
I believe the answer is:
unhook
'free' is the definition.
(I've seen this before)
'new hampshire pair at lord's visiting this country' is the wordplay.
'new hampshire' becomes 'NH' (abbreviation).
'pair' shows that letters should be duplicated.
'at lord' becomes 'o' (I can't justify this - if you can you should believe this answer much more).
'visiting' indicates putting letters inside.
'this country' becomes 'UK' (from the perspective of a British newspaper).
'o' duplicated is 'oo'.
'nh'+'oo'='nhoo'
'nhoo' going into 'uk' is 'UNHOOK'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for unhook that I've seen before include "Unfasten" , "Free" , "Release catch" , "Detach" , "Lift off the sharp bent line" .)
