Without any clear plan, Henry cut off fire hydrant foolishly (6)
I believe the answer is:
adrift
'foolishly' is the definition.
Both the answer and definition are adverbs. Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for adrift that I've seen before include "getting nowhere?" , "Purposeless" , "Disoriented" , "out of touch" , "No longer fixed in position" .)
