To catch horse, frenzied dame ran (7)
I believe the answer is:
managed
'ran' is the definition.
(I've seen this before)
'to catch horse frenzied dame' is the wordplay.
'to catch' means one lot of letters goes inside another.
'horse' becomes 'nag' (nag is a kind of horse).
'frenzied' is an anagram indicator.
'dame' anagrammed gives 'maed'.
'nag' placed within 'maed' is 'MANAGED'.
(Other definitions for managed that I've seen before include "Contrived" , "Coped" , "Ran, administered" , "Controlled, was in charge of" , "Supervised (staff)" .)
