Requirements to send deviously out East (5)
I believe the answer is:
needs
'requirements' is the definition.
('need' can be a synonym of 'requirement')
'send deviously out east' is the wordplay.
'deviously' indicates an anagram (I've seen this in other clues).
'out' indicates putting letters inside.
'east' becomes 'e' ('E' can be a synonym of 'east').
'send' anagrammed gives 'neds'.
'neds' going around 'e' is 'NEEDS'.
'to' acts as a link.
(Other definitions for needs that I've seen before include "Is desperate for" , "shopping-list, say" , "Necessities" , "Wants, requires" , "Misses" .)
