Zoomed, for example, Review for school classes (6)
I believe the answer is:
ranges
'classes' is the definition.
The definition and answer can be both human attributes as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'zoomed for example review for school' is the wordplay.
'zoomed' becomes 'ran' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'review' says the letters should be written in reverse.
'for' means one lot of letters go next to another.
'school' becomes 's'.
'eg' in reverse letter order is 'ge'.
'ran'+'ge'+'s'='RANGES'
Can you help me to learn more?
(Other definitions for ranges that I've seen before include "Areas for target practice" , "Kitchen appliances and large, grassy tracts" , "Areas for shooting practice" , "rows" , "Large tracts of open land" .)
