Work at the trade of laminating wood? (3)
I believe the answer is:
ply
'work at' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ply that I've seen before include "Work steadily as at one's trade" , "drama one's missed" , "Strand, of wool or wood, say" , "Laminate thickness" , "This wood is laminated" .)
