Tail of a swallow near the ground (3)
I believe the answer is:
low
This clue could be a double definition.
'tail of a swallow' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'near the ground' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for low that I've seen before include "SECOND PART OF 14" , "Deep sound made by cattle" , "Without great height" , "sound from Hereford?" , "Deep sound of cattle - not high" .)
