Queen single in start cut being faulty (9)
I believe the answer is:
erroneous
'faulty' is the definition.
(thesaurus)
'queen single in start cut' is the wordplay.
I cannot quite understand how this works, but
'queen' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is found within the answer.
'single' could be 'one' (I've seen this before) and 'one' is located in the answer.
This explanation may well be incorrect...
'being' is the link.
Can you help me to learn more?
(Other definitions for erroneous that I've seen before include "Mistaken - inaccurate" , "Incorrect, wrong" , "Mistaken, in error" , "with mistakes" , "not right" .)
