Move smartly in a tango with a charmer (6)
I believe the answer is:
twitch
'move smartly' is the definition.
'twitch' can be an answer for 'move' (twitching is a kind of moving). I'm not certain of the 'smartly' bit.
'a tango with a charmer' is the wordplay.
'a tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'with' is a charade indicator (letters next to each other).
'a charmer' becomes 'witch' (someone who charms).
't'+'witch'='TWITCH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for twitch that I've seen before include "grass" , "One may be nervous" , "Move spasmodically" , "Sudden muscular spasm" , "Move uncontrollably - watch birds" .)
