Suffer cut, extremely severe? Veins possibly gush (12)

I believe the answer is:

effusiveness

'gush' is the definition.
(thesaurus)

'suffer cut extremely severe? veins possibly' is the wordplay.
'cut' means to remove the last letter.
'extremely' suggests removing the centre.
'possibly' indicates anagramming the letters.
'severe' with its middle taken out is 'se'.
'suffer' with its final letter removed is 'suffe'.
'suffe'+'se'+'veins'='suffeseveins'
'suffeseveins' anagrammed gives 'EFFUSIVENESS'.

(Another definition for effusiveness that I've seen is " Ebullience".)

I've seen this clue in The Independent.
