Ant and Dec finally speak after two pages (10)
I believe the answer is:
leafcutter
'ant' is the definition.
(I've seen this before)
'dec finally speak after two pages' is the wordplay.
'finally' says to take the final letters.
'speak' becomes 'utter' (synonyms).
'after' is a charade indicator (letters next to each other).
'two pages' becomes 'leaf' (I've seen this before).
The last letter of 'dec' is 'c'.
'c'+'utter'='cutter'
'cutter' put after 'leaf' is 'LEAFCUTTER'.
'and' is the link.
(Other definitions for leafcutter that I've seen before include "Type of insect" , "Ant" , "whose bite could make Adam and Eve red?" .)
