erstwhile
No longer current
Erstwhile means former—describing something or someone that once held a particular role or status but no longer does: his erstwhile business partner, the erstwhile capital of the empire.
The word sounds literary and slightly old-fashioned, lending a formal or ironic tone.
Occasionally used as an adverb meaning formerly, though this is rare in contemporary English.
