Work on a loom (5)
I believe the answer is:
weave
'work on a loom' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for weave that I've seen before include "move from side to side" , "Combine into a whole" , "Use a loom" , "Make by interlacing" , "Interlace strands of material" .)
