Burden with logs (6)
I believe the answer is:
lumber
This might be a double definition.
'burden' is the first definition.
(thesaurus)
'with logs' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
Can you help me to learn more?
(Other definitions for lumber that I've seen before include "Clumsily move - junk" , "Walk heavily carrying wood?" , "Burden with an unwanted task" , "Wood cut and prepared as building material" , "Unwanted furniture" .)
