Knowledge left grannie in a tizz (8)
I believe the answer is:
learning
'knowledge' is the definition.
(I know that learning is a type of education)
'left grannie in a tizz' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is found in the answer.
an anagram of 'grannie' is 'earning' which is present in 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 learning that I've seen before include "Researching - scholarship" , "Discovering, finding out" , "Acquired knowledge" , "A little of it is said to be a dangerous thing" , "Lore" .)
