'alberca' originates from Arabic, specifically the word 'al-birka', where 'al-' meant 'the' and 'birka' meant 'pool'.

'al-birka' transformed into the Spanish word 'alberca', and eventually became used in English to refer to a swimming pool in Spanish-speaking regions.

Initially, it meant 'a pool of water', but over time it evolved into its current meaning of 'a swimming pool'.
