The gentleman and I brought her back (4)
I believe the answer is:
iris
'her back' is the definition.
I can't tell whether this defines the answer.
'the gentleman and i' is the wordplay.
'the gentleman' becomes 'ris' (I am not sure about this - if you are sure you should believe this answer much more).
'and' says to put letters next to each other.
'ris' put after 'i' is 'IRIS'.
'brought' acts as a link.
Can you help me to learn more?
(Other definitions for iris that I've seen before include "In the middle of which pupil is opening" , "Plant - part of the eye" , "Garden flower - part of eye" , "Ms Murdoch" , "Eye diaphragm" .)
