It's heard to give a different result (6)
I believe the answer is:
rustle
'it's heard to' is the definition.
I can't tell whether this defines the answer.
'a different result' is the wordplay.
'a different' is an anagram indicator.
'result' with letters rearranged gives 'RUSTLE'.
'give' is the link.
Can you help me to learn more?
(Other definitions for rustle that I've seen before include "making little noise" , "Swish - lustre (anag)" , "Swish - steal cattle" , "Steal cattle or livestock with whispering sound" , "Steal 2" .)
