Somewhat green and barely in charge of a class (7)
I believe the answer is:
generic
'somewhat green and barely in charge of a class' is the definition.
I can't judge whether this defines the answer.
'green and barely in charge of a class' is the wordplay.
I cannot quite see how this works, but
an anagram of 'green' is 'gener' which is within the answer.
'in charge' could be 'ic' (abbreviation for 'in charge') and 'ic' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for generic that I've seen before include "Of a whole group or kind" , "not proprietary" , "of a particular type" , "Non-proprietary (drug)" , "Non-specific" .)
