Old Tagalog (Tagalog: Lumang Tagalog; Baybayin: pre-virama: ᜎᜓᜋ ᜆᜄᜎᜓ, post-virama [krus kudlit]: ᜎᜓᜋᜅ᜔ ᜆᜄᜎᜓᜄ᜔; post-virama [pamudpod]: ᜎᜓᜋᜅ᜴ ᜆᜄᜎᜓᜄ᜴), is the earliest form of the Tagalog language during the Classical period. It is the primary language of pre-colonial Tondo, Namayan and Maynila. The language originated from the Proto-Philippine language and evolved to Classical Tagalog, which was the basis for Modern Tagalog. Old Tagalog uses the Tagalog script or Baybayin, one of the scripts indigenous to the Philippines.
