Prudence gives misleading directions (10)
I believe the answer is:
discretion
'prudence' is the definition.
(synonyms)
'misleading directions' is the wordplay.
'misleading' indicates an anagram (I've seen this in other clues).
'directions' with letters rearranged gives 'DISCRETION'.
'gives' is the link.
(Other definitions for discretion that I've seen before include "Tactful quality" , "Diplomacy" , "The better part of valour" , "Tact - prudence" , "Liberty to act at pleasure; prudence" .)
