Crossword Genius

Carrying out of extreme sentence (9)

Ross

I believe the answer is:

execution

I believe this is a double definition.

'carrying out' is the first definition.
(synonyms)

'extreme sentence' is the second definition.
(sentence of death)

'of' acts as a link.

(Other definitions for execution that I've seen before include "The carrying out of" , "Topping" , "Eg, beheading" , "style of musical performance" , "Queen of Hearts' order" .)

I've seen this clue in The Times.
