Owl flying around at no great altitude (3)
I believe the answer is:
low
'no great altitude' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's a link between them I don't understand?
'owl flying around' is the wordplay.
'flying around' indicates anagramming the letters.
'owl' anagrammed gives 'LOW'.
'at' is the link.
Can you help me to learn more?
(Other definitions for low that I've seen before include "Deep sound of cattle - not high" , "Depressed or base" , "Deep sound made by cattle" , "Make a cow-like noise" , "Without great height" .)
