Taught trust to friends, oddly (7)
I believe the answer is:
tutored
'taught' is the definition.
(synonyms)
'trust to friends oddly' is the wordplay.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
'trust'+'to'+'friends'='trusttofriends'
The alternating letters of 'trusttofriends' are 'TUTORED'.
(Other definitions for tutored that I've seen before include "Coached" , "Privately taught" , "Taught small groups" , "Disciplined" , "Was coach" .)
