Nominally the part of Aphrodite (3)

I believe the answer is:

rod

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

'nominally the part' is the definition.
I can't judge whether this defines the answer.

'of aphrodite' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ROD' can be found hidden inside 'aphrodite'.

Can you help me to learn more?

(Other definitions for rod that I've seen before include "Little boy" , "Measurement" , "A few yards" , "Flexible stick for 11 Down" , "Staff" .)

I've seen this clue in the Evening Standard.
