A burden to shoulder (3)
I believe the answer is:
hod
This could be a double definition.
'a burden' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'shoulder' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'to' is the link.
Can you help me to learn more?
(Other definitions for hod that I've seen before include "Trough on pole used by bricklayer to carry things" , "Brick-carrier's holder" , "A bricklayer's carrying pole" , "Coal scuttle" , "Bricklaver's carrier of orthodox kind" .)
