Marguerita throttles one having row (6)
I believe the answer is:
arguer
'row' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'marguerita throttles one having' is the wordplay.
'one having' indicates a hidden word.
'ARGUER' is hidden within 'marguerita throttles'.
Can you help me to learn more?
(Other definitions for arguer that I've seen before include "He reasons" , "One in dispute" , "One engages in debate" .)
