Curse macho way of talking (11)
I believe the answer is:
malediction
'curse' is the definition.
(malediction is a kind of curse)
'macho way of talking' is the wordplay.
I cannot quite see how this works, but
'macho' could be 'male' (I've seen this in another clue) and 'male' is located in the answer.
'way' could be 'diction' (I have seen 'Way of speaking' mean 'diction' so perhaps 'way' could also mean 'diction') and 'diction' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for malediction that I've seen is " Calling down a curse - lime not acid (anag)".)
