Recommendation - possibly interlaced (10)
I believe the answer is:
credential
'recommendation' is the definition.
(thesaurus)
'possibly interlaced' is the wordplay.
'possibly' indicates an anagram.
'interlaced' is an anagram of 'CREDENTIAL'.
(Other definitions for credential that I've seen before include "Qualification (indicating a person's suitability)" , "proof of entitlement" , "Official introductory letter" , "Interlaced (anag.)" .)
