Keeps providing support (5)
I believe the answer is:
stays
This clue might be a double definition.
'keeps' is the first definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'support' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for stays that I've seen before include "Boards, lodges" , "Remains (in place)" , "Stanchions" , "Remains; support wires" , "Remains; supporting wires" .)
