IPA: /ˈpɒʃli/

In a manner that is elegant, luxurious, or associated with the upper class.
She dressed poshly for the gala event.
'Posh' (of uncertain origin, possibly from Romani 'posh' meaning 'half' or 'half a pound') and '-ly' (a suffix used to form adverbs). The word 'poshly' means in a manner that is elegant or luxurious, often associated with wealth.
Think of 'posh' as something that is elegant or luxurious, and remember that adding '-ly' means it describes how something is done. So, 'poshly' means doing something in an elegant or luxurious way.
