What does erst mean?
Erst is an archaic English adverb meaning 'at first' or 'formerly,' used to indicate that something held true initially or in the past. It appears chiefly in older literature, poetry, and historical prose, lending a deliberately antique or formal flavor to a sentence. A writer might say 'the erst capital of the kingdom' to mean its original or former capital, though modern readers would more naturally encounter the surviving derivative 'erstwhile,' which functions as an adjective meaning 'former.' The word descends from Old English and is closely related to the German adverb 'erst,' which remains in active use there with meanings such as 'first' or 'not until.' Because 'erst' is no longer part of ordinary speech, using it today signals either quotation from an older text or a conscious stylistic choice to evoke the past. Its value for contemporary readers lies mainly in understanding historical writing and appreciating how English preserves fragments of older vocabulary inside compounds.
adverbArchaic term meaning 'first of all' or 'at first'; formerly, originally.
- At first; first of all (archaic).
- Formerly; once (archaic).
"The castle's erst inhabitants left behind few traces of their daily lives."
"The erst ruler of the province was remembered fondly by the villagers."
"She spoke of the town as it stood erst, long before the highway arrived."
'Erst' survives today mostly as a fossil inside 'erstwhile' — but it was once the everyday English word for 'at first,' and its German cousin 'erst' still does the job.

Etymology of erst
Erst derives from Old English 'ǣrest,' the superlative form of 'ǣr,' meaning 'before' or 'earlier,' making it a doublet in sense of 'early' and a cousin of 'ere.' It is cognate with the modern German adverb 'erst,' which retains active use. Over time English largely abandoned 'erst' except in the compound 'erstwhile,' which preserves its meaning of 'former.'
