Sort of pause, being knocked up (8)
I believe the answer is:
pregnant
I believe this clue is a double definition.
'sort of pause' is the first definition.
(as in a pregnant pause)
'being knocked up' is the second definition.
(thesaurus)
(Other definitions for pregnant that I've seen before include "full of implications" , "Expecting a baby" , "With child, enceinte" , "Gravid" , "loaded" .)
