Go off most unattached female misses (5)
I believe the answer is:
reest
'go' is the definition.
Both the answer and definition are verbs in their base form.

I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for reest that I've seen before include "In Scotland, fit" , "Cure for Scot" .)
