Turn silent and go out for a tool (7)
I believe the answer is:
utensil
'for a tool' is the definition.
(I've seen this before)
'turn silent and go out' is the wordplay.
'turn' is an anagram indicator.
'and' says to put letters next to each other.
'go out' becomes 'u' (I can't justify this - if you can you should give a lot more credence to this answer).
'silent' is an anagram of 'tensil'.
'tensil' put after 'u' is 'UTENSIL'.
Can you help me to learn more?
(Other definitions for utensil that I've seen before include "Implement for practical use" , "Can opener, for example" , "A container for kitchen use" , "vessel" , "knife, maybe" .)
