Start being a socialite? (5)

I believe the answer is:

debut

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

'start' is the definition.
(debut is a kind of start)

'being a socialite?' is the wordplay.
'being' becomes 'deb' (deb is a kind of being).
'a socialite?' becomes 'ut' (I am not sure about this - if you are sure you should believe this answer much more).
'deb'+'ut'='DEBUT'

Can you help me to learn more?

(Other definitions for debut that I've seen before include "First public appearance of performer" , "where one began" , "entrance" , "Introduction" , "Start -- launch" .)

I've seen this clue in the Evening Standard.
