Desert wanderer blew Te Deum badly (10)
I believe the answer is:
tumbleweed
'desert wanderer' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'blew te deum badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'blew'+'te'+'deum'='blewtedeum'
'blewtedeum' is an anagram of 'TUMBLEWEED'.
Can you help me to learn more?
(Other definitions for tumbleweed that I've seen before include "Plant blown as a dry ball by the wind" , "Plant that blows around in the wind" , "Plant of arid regions, rolled about by the wind" , "Ball-like remains of plant blown by prairie winds" , "Western drifter" .)
