In my opinion one of the main uses of 'pure' is to soften a command to be more a request
entra - come in
entra pure - please do come in
mi dica? - may I help you?
mi dica pure? - please, how may I help you?
I know that 'mica' has something to do with negation but I do not know how to use it
any help would be appreciated
