It's not common, ordinary character ditching upturned luge (6)
I believe the answer is:
rarity
'upturned luge' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'it's not common ordinary character ditching' is the wordplay.
I cannot really see how this works, but
'it's' could be 'it' (I've seen this in other clues) and 'it' is located in the answer.
'character' could be 'y' and 'y' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rarity that I've seen before include "Uncommon item or event" , "You don't see it very often" , "Unusual specimen" , "Uncommonness" , "something quite unusual" .)
