Gave wrong account of my boss supporting girl reportedly dealing with gift (14)
I believe the answer is:
misrepresented
'gave wrong account' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'my boss supporting girl reportedly dealing with gift' is the wordplay.
'my boss' becomes 'ed' (abbreviation for editor, the setter's boss).
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'girl reportedly' becomes 'mis' (I can't justify this - if you can you should give a lot more credence to this answer).
'dealing with' becomes 're' (regarding).
'gift' becomes 'present' (present is a kind of gift).
'mis'+'re'+'present'='misrepresent'
'ed' put after 'misrepresent' is 'MISREPRESENTED'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for misrepresented that I've seen before include "Gave a false account of" , "produced false accounts" , "Gave wrong impression" , "Hospital department" .)
