Word Origin & Etymology

First recorded in the early 20th century, 'posh' likely derives from 19th-century British slang meaning 'money' or a 'dandy.' The popular story that it is an acronym for 'port out, starboard home' (referring to the cooler, shaded cabins on steamships traveling between Britain and India) is a folk etymology with no historical evidence.
