Old French taxes extended? Or cut at the end (8)
I believe the answer is:
'old french taxes extended?' is the definition.
I can't judge whether this defines the answer.
'cut at the end' is the wordplay.
'cut' becomes 'tail' (tailing is a kind of cutting).
'at the end' becomes 'less' (I can't justify this - if you can you should give a lot more credence to this answer).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for tailless that I've seen before include "Like frogs and toads, say" , "Physical characteristic of Manx cat" , "Physical condition of Manx cat" .)
