malediction

I'm a little stuck... Click here to teach me more about this clue!

'cursing' is the definition.
(I know that malediction is a type of cursing)

'men's speech' is the wordplay.
'men's' becomes 'male' (I can't explain this - if you can you should give a lot more credence to this answer).
'speech' becomes 'diction' (I've seen this in other clues).
'male'+'diction'='MALEDICTION'

'is full of' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Another definition for malediction that I've seen is " Calling down a curse - lime not acid (anag)".)

I've seen this clue in The Irish News.
