osier

I'm a little stuck... Click here to teach me more about this clue!

'basket maker' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for osier that I've seen before include "Willow for basket-making" , "may be a bit of a basket" , "Tree for basket making" , "Withy" , "Basketry willow" .)

I've seen this clue in The Times.
