Conversation about right map (5)
I believe the answer is:
chart
'map' is the definition.
(I know that chart is a more specific form of the action map)
'conversation about right' is the wordplay.
'conversation' becomes 'chat' (chat is a kind of conversation).
'about' is an insertion indicator.
'right' becomes 'r' (abbreviation).
'chat' going around 'r' is 'CHART'.
(Other definitions for chart that I've seen before include "series of plots?" , "Nautical map" , "Table or graph" , "Map to assist navigation by sea" , "Navigational map" .)
