I rose perhaps in the basket-making trade (5)
I believe the answer is:
osier
'basket-making trade' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'i rose perhaps in' is the wordplay.
'perhaps' indicates anagramming the letters.
'in' indicates putting letters inside.
'rose' with letters rearranged gives 'oser'.
'i' placed into 'oser' is 'OSIER'.
'the' is the link.
Can you help me to learn more?
(Other definitions for osier that I've seen before include "Willow growing shoots used in basketwork" , "Kind of willow used in basketwork" , "Basket-maker's willow" , "Salix" , "Basket-maker" .)
