Tesla truck transports construction material (4)
I believe the answer is:
slat
'construction material' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'tesla truck transports' is the wordplay.
'SLAT' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for slat that I've seen before include "Part of a Venetian blind" , "Thin strip" .)
