Loud sob about one tore us sadly (10)
I believe the answer is:
boisterous
'loud' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'sob about one tore us sadly' is the wordplay.
'about' means one lot of letters go next to another.
'one' becomes 'i' (roman numeral).
'sadly' is an anagram indicator.
'i'+'tore'+'us'='itoreus'
'sob' after 'itoreus' is 'itoreussob'.
'itoreussob' with letters rearranged gives 'BOISTEROUS'.
Can you help me to learn more?
(Other definitions for boisterous that I've seen before include "Noisy and lively" , "Exuberant" , "rollicking" .)
