Slicker fiction in Republic of Ireland rewritten (6)
I believe the answer is:
oilier
'slicker' is the definition.
Both the answer and definition are comparative adjectives. Perhaps there's an association between them I don't understand?
'fiction in republic of ireland rewritten' is the wordplay.
I cannot quite see how this works, but
'fiction' could be 'lie' (I've seen this in other clues) and 'lie' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'ireland' could be 'ir' (I've seen this in other clues) and 'ir' is located in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oilier that I've seen before include "More lubricated or flattering" , "rather greasy" , "More oleaginous" , "More viscous or smooth in manner" , "More viscous or unpleasantly smooth" .)
