How silly of me to overturn this carrying trough (3)
I believe the answer is:
hod
'trough' is the definition.
(a hod is a trough used by a builder)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hod that I've seen before include "Brick-layer's tool" , "Trough on pole for carrying bricks" , "A bricklayer carries bricks on it" , "Bricklaver's carrier of orthodox kind" , "A bricklayer's carrying pole" .)
