Drown out American hosting ball? That's strange (8)
I believe the answer is:
wondrous
'strange' is the definition.
(thesaurus)
'drown out american hosting ball?' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'american' becomes 'US' (abbreviation for United States).
'hosting' means one lot of letters goes inside another (inserted letters are welcomed in or hosted).
'ball?' becomes 'o' (O looks like a ball).
'drown' anagrammed gives 'wondr'.
'wondr'+'us'='wondrus'
'wondrus' placed around 'o' is 'WONDROUS'.
'that's' is the link.
(Other definitions for wondrous that I've seen before include "Amazing" , "Awesome" , "Inspiring a feeling of delight" .)
