Change gears, points and lubricants (7)
I believe the answer is:
greases
'lubricants' is the definition.
The answer and definition can be both substances as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'change gears points' is the wordplay.
'change' is an anagram indicator.
'points' becomes 'Es' (two compass points).
'gears' with letters rearranged gives 'greas'.
'greas'+'es'='GREASES'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for greases that I've seen before include "Lubricates" , "Bribes" , "One of those animal products" .)
