Awkward truant is one who is unsuited? (8)
I believe the answer is:
'one who is unsuited?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'awkward truant is' is the wordplay.
'awkward' is an anagram indicator.
'truantis' anagrammed gives 'NATURIST'.
Can you help me to learn more?
(Other definitions for naturist that I've seen before include "One practices nudity" , "Person who goes naked in designated areas" , "one barely feeling comfortable" , "One who believes in going nude" , "One who goes naked" .)
