Commit to getting into persistent rust (7)
I believe the answer is:
entrust
'commit' is the definition.
(I know that commit can be written as entrust)
'getting into persistent rust' is the wordplay.
'ENTRUST' is hidden within the letters.
But, I am unsure how this is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for entrust that I've seen before include "Invest, commit" , "Nutters (anag)" , "Give as responsibility, place in care of" , "Put into someone's care" , "Give for safekeeping" .)
