Excellent moor offered up as space to learn (9)
I believe the answer is:
classroom
'space to learn' is the definition.
I can't judge whether this defines the answer.
'excellent moor offered up' is the wordplay.
'excellent' becomes 'class' (I've seen this before).
'offered up' says the letters should be written in reverse.
'moor' back-to-front is 'room'.
'class'+'room'='CLASSROOM'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for classroom that I've seen before include "place of education" , "Part of a school" , "Where children learn" , "School space" , "Teaching environment" .)
