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

'potential parts for child' is the definition.
I can't judge whether this definition defines the answer.

'star not including lead part?' is the wordplay.
'star' becomes 'icon'.
'not' suggests deleting specific letters.

'icon' with 'inc' removed is 'o'.

I've seen this clue in The Independent.
