He will tip off a woman (4)
I believe the answer is:
ella
'a woman' is the definition.
'he will tip off' is the wordplay.
'tip' indicates one should take the final letters.
'off' becomes 'la' (I can't explain this - if you can you should give a lot more credence to this answer).
The final letters of 'he will' are 'el'.
'el'+'la'='ELLA'
Can you help me to learn more?
(Other definitions for ella that I've seen before include "Woman" , "Girl" , "Great late jazz singer . . . . Fitzgerald" , ".... Fitzgerald, late great jazz diva" , "- Wheeler Wilcox, US poet" .)
