Fever about arranged loan that's not digital (8)
I believe the answer is:
analogue
'that's not digital' is the definition.
(I've seen this before)
'fever about arranged loan' is the wordplay.
'fever' becomes 'ague' (I've seen this before).
'about' indicates putting letters inside.
'arranged' is an anagram indicator (letters rearranged).
'loan' with letters rearranged gives 'nalo'.
'ague' placed around 'nalo' is 'ANALOGUE'.
(Other definitions for analogue that I've seen before include "Type of transmission by radio waves without digital conversion" , "a continuous watch" , "Traditional type of watch with face and hands" , "Something similar in certain respects to another" , "This is similar in some respects to something else" .)
