Certain about including right individual blood type. Wrong (9)
I believe the answer is:
erroneous
'wrong' is the definition.
(I know that wrong can be written as erroneous)
'certain about including right individual blood type' is the wordplay.
'certain' becomes 'sure' (synonyms).
'about' is a reversal indicator.
'including' is an insertion indicator.
'right individual blood type' becomes 'roneo' (I can't justify this - if you can you should give a lot more credence to this answer).
'sure' written backwards gives 'erus'.
'erus' enclosing 'roneo' is 'ERRONEOUS'.
Can you help me to learn more?
(Other definitions for erroneous that I've seen before include "Incorrect, wrong" , "not right" , "with mistakes" , "Mistaken - inaccurate" , "Mistaken, in error" .)
