Translation I put out in passing (12)
I believe the answer is:
transitional
'passing' is the definition.
(thesaurus)
'translation i put out' is the wordplay.
'put out' indicates an anagram.
'translation'+'i'='translationi'
'translationi' with letters rearranged gives 'TRANSITIONAL'.
'in' is the link.
(Other definitions for transitional that I've seen before include "In process of change" , "In process of changing" , "Temporary" .)
