Phone’s yet to be adapted for novices (9)
I believe the answer is:
neophytes
'novices' is the definition.
(neophyte is a kind of novice)
'phone's yet to be adapted' is the wordplay.
'to be adapted' is an anagram indicator.
'phones'+'yet'='phonesyet'
'phonesyet' is an anagram of 'NEOPHYTES'.
'for' acts as a link.
(Other definitions for neophytes that I've seen before include "Novices" , "Newcomers" .)
