Binder for lubricant of lifts (5)
I believe the answer is:
folio
'binder' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'lubricant of lifts' is the wordplay.
'lubricant' becomes 'oil' (I've seen this before).
'lifts' is a reversal indicator (I've seen 'lifted' mean this (going up in down clue)).
'oil'+'of'='oilof'
'oilof' written backwards gives 'FOLIO'.
'for' is the link.
Can you help me to learn more?
(Other definitions for folio that I've seen before include "Book size" , "Leaf of book - page number" , "Body of written work" , "eaf" , "Sheet of paper folded to make two book leaves" .)
