Couple saddled with this? (6)
I believe the answer is:
tandem
'couple saddled with this?' is the definition.
The definition suggests a singular noun which matches the answer.
'with this?' is the wordplay.
I cannot really understand how this works, but
'with' could be 'and' and 'and' is present in the answer.
The remaining letters 'tem' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tandem that I've seen before include "Two-person bike" , "Two-seater bike" , "Bike with two saddles" , "it's not normally what one rides" , "Bicycle-built-for-two" .)
