'ayuntamiento' originates from Spanish, specifically the word 'ayuntar,' where 'a-' meant 'to' and 'juntar' meant 'to join.'

'ayuntar' transformed into the Spanish word 'ayuntamiento,' and it has remained largely unchanged in modern usage.

Initially, it meant 'a gathering or joining together,' but over time it evolved into its current meaning of 'town hall or city council.'
