Adrift, runs like bull (as opposed to cow)? (10)
I believe the answer is:
rudderless
'adrift' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rudderless that I've seen before include "Unable to provide guidance" , "Without steering mechanism" , "Lacking direction" , "Having lost control" , "not yielding power to steer" .)
