'has-been' originates from English, specifically the phrase 'has been' (present perfect of 'be'), where the literal sense is that something 'has existed or occurred in the past.'

'has-been' developed from the two-word phrase 'has been' used in ordinary grammar; over time it was reinterpreted and turned into a compound noun (often hyphenated) meaning 'someone who has been (something)' and came to be used contemptuously around the early 20th century.

Initially it referred literally to the present perfect ('has been' + participle); over time it became a noun meaning 'one who was once successful or prominent but no longer is,' acquiring a derogatory sense.
