A grade from this? (1,5)
I believe the answer is:
a level
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'a grade' is the wordplay.
'grade' becomes 'level' (synonyms).
'a'+'level'='A-LEVEL'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for a level that I've seen before include "Sixth-form exam" , "School qualification" , "Advanced exam" , "Top tier in UK schools" , "Final exam for students at secondary school" .)
