Direction for most uncomplicated tango (4)
I believe the answer is:
east
'direction' is the definition.
(compass direction)
'most uncomplicated tango' is the wordplay.
'most' means to remove the last letter.
'uncomplicated' becomes 'easy' (similar in meaning).
'tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'easy' with its last letter removed is 'eas'.
'eas'+'t'='EAST'
'for' is the link.
(Other definitions for east that I've seen before include "Bridge player" , "Tom's schoolfellow" , "Compass point at 90 degrees" , "An opponent of North" , "Opposite of west" .)
