Crossword Genius

As a result, the byre collapsed (7)

Ross

I believe the answer is:

thereby

'as a result' is the definition.
(I've seen this before)

'the byre collapsed' is the wordplay.
'collapsed' indicates anagramming the letters.
'byre' anagrammed gives 'reby'.
'the'+'reby'='THEREBY'

(Other definitions for thereby that I've seen before include "For that reason" , "about that amount" , "In consequence" , "By that means" , "As a result of that" .)

I've seen this clue in The Telegraph.
