Displacement of a person to Rome, possibly (7)
I believe the answer is:
removal
'displacement' is the definition.
(thesaurus)
'a person to rome possibly' is the wordplay.
'a person' becomes 'val' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'possibly' is an anagram indicator.
'rome' is an anagram of 'remo'.
'val' put after 'remo' is 'REMOVAL'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for removal that I've seen before include "The taking (of something) to another place" , "Extraction" , "Transferral" , "Transference" , "Sack" .)
