Adult tie designed for freedom of movement (8)
I believe the answer is:
latitude
'freedom of movement' is the definition.
'latitude' can be an answer for 'freedom' (latitude is a kind of freedom). I am not sure about the 'of movement' bit.
'adult tie designed' is the wordplay.
'designed' indicates an anagram (designed with the letters).
'adult'+'tie'='adulttie'
'adulttie' is an anagram of 'LATITUDE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for latitude that I've seen before include "Compass - allowance - tolerance" , "global cover to some degree?" , "Poles' approach increases such" , "Liberality" , "Room to manoeuvre or distance from equator" .)
