Digital display's meaning is vague and a bit elevated (1,4)
I believe the answer is:
v sign
'digital display's' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'meaning is vague and a bit elevated' is the wordplay.
'a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'elevated' shows that the letters should be reversed in order (in a down clue, letters go up).
'ngisv' can be found hidden inside 'meaning is vague and'.
'ngisv' backwards is 'V-SIGN'.
Can you help me to learn more?
(Other definitions for v sign that I've seen before include "Rude gesture" , "small number in Rome" , "Obscene gesture" , "Offensive gesture" , "Winning indication" .)
