Caught up with Dynasty and got ahead (7)
I believe the answer is:
tangled
'caught up' is the definition.
'dynasty and got ahead' is the wordplay.
'dynasty' becomes 'tang' (Chinese dynasty).
'and' says to put letters next to each other.
'got ahead' becomes 'led' (to lead is to be ahead).
'tang'+'led'='TANGLED'
'with' acts as a link.
(Other definitions for tangled that I've seen before include "Caught" , "Confusedly matted" , "Confusedly twisted" , "Twisted into confused mass" , "Knotty; snarled" .)
