He gets carried away (5)
I believe the answer is:
rider
'he gets carried away' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'der' and 'der' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rider that I've seen before include "H. - Haggard, English novelist (She, etc)" , "supported by an Arab, perhaps" , "Condition added to something already agreed" , "qualification" , "recommendation made in court" .)
