Sign of approval of extremely practical check (7)

Ross

I believe the answer is:

plaudit

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

'sign of approval' is the definition.
'plaudit' can be an answer for 'approval' (plaudit is a kind of approval). I'm unsure of the 'sign of' bit.

'extremely practical check' is the wordplay.
'extremely' says to hollow out the word (remove centre letters).
'check' becomes 'audit' (I've seen this before).
'practical' with its centre taken out is 'pl'.
'pl'+'audit'='PLAUDIT'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for plaudit that I've seen before include "Salute" , "Praise, encomium" , "Commendation, acclamation" , "Acclaim" , "Cheer" .)
