Impersonation makes Rodolfo's lover weep (7)

I believe the answer is:

mimicry

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

'impersonation' is the definition.
(I know that mimicry is a type of impersonation)

'rodolfo's lover weep' is the wordplay.
'rodolfo's lover' becomes 'mimi' (I can't explain this - if you can you should believe this answer much more).
'weep' becomes 'cry' (synonyms).
'mimi'+'cry'='MIMICRY'

'makes' is the link.

Can you help me to learn more?

(Other definitions for mimicry that I've seen before include "Taking off" , "Burlesque" , "Skill of copying another" , "Parody" , "Copycat behaviour" .)

I've seen this clue in the Sydney Morning Herald.
