Tagalog language - Wikipedia, the free encyclopedia: "Batangas is the heartland of the Tagalog language, and so, the Tagalog spoken here closely resembles Old Tagalog better than the other dialects. Words of Sanskrit, Arabic, and Persian origin are still used. Its intonation is quite different from that of Manila, Batangan Tagalog being spoken fast and with a thick accent. Area: Batangas"
