A number rule out showing charm (6)

Ross

I believe the answer is:

allure

'charm' is the definition.
(I've seen this before)

'a number rule out' is the wordplay.
'number' becomes 'l' (L is an example**).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'rule' with letters rearranged gives 'lure'.
'a'+'l'+'lure'='ALLURE'

'showing' acts as a link.

(Other definitions for allure that I've seen before include "Charm, magnetism" , "There's glamour" , "Powerful attraction" , "Glamorous appeal" , "Attractiveness, glamour" .)

I've seen this clue in The Telegraph.
