Very good odds on loan I finally arranged (8)
I believe the answer is:
splendid
'very good' is the definition.
(thesaurus)
'odds on loan i finally arranged' is the wordplay.
'odds' becomes 'sp' (betting abbreviation for starting price).
'on' says to put letters next to each other.
'loan' becomes 'lend' ('lend' can be a synonym of 'loan'**).
'finally' says to take the final letters.
The final letter of 'arranged' is 'd'.
'sp'+'lend'+'i'+'d'='SPLENDID'
(Other definitions for splendid that I've seen before include "Magnificent, very impressive" , "super" , "Grand" , "Excellent, first-class" , "Very fine, glorious" .)
