Detached wanderer's stomach produced wind before religious festival, reportedly (10)
I believe the answer is:
tumbleweed
'detached wanderer's stomach' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tumbleweed that I've seen before include "Plant of arid regions, rolled about by the wind" , "Plant swept along by the wind - wet Elbe mud (anag)" , "Ball-like remains of plant blown by prairie winds" , "Plant that blows around in the wind" , "Western drifter" .)
