This is a question specifically about Pathfinder Society (Second Edition) Characters.
If you create a Pathfinder Society Character, you get Common (Taldan) as starting language as well as access to the regional language of the region / country / area your character hails from. Regional Languages are listed here: Regional Languages
What regional language do you gain access to if your character grew up in Absalom? The wording
Nearly every language listed here is spoken on the melting-pot streets of Absalom.
suggests that you can actually chose every regional language as "your" regional language, but I can't find any other information about this except this short sentence.
