Does it not strike you as a stately abbreviation? (4)
I believe the answer is:
miss
'abbreviation?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for miss that I've seen before include "Fail to perceive" , "Fail; long for" , "Don't hit" , "Fail to meet - girl" , "Fail to find" .)
