Tagalog, also known as Filipino, is an Austronesian language spoken in the Philippines. It serves as the basis for the official standardised form of Filipino, which is one of the two official languages of the Philippines, the other being English. Tagalog is the first language of a significant portion of the Philippine population and is widely used in media, education, and government.

The language has a rich history and cultural significance, playing a crucial role in the country’s literature, arts, and heritage. Tagalog is written using the Latin script, and its phonology includes a set of 20 consonants and 16 vowels. Like many Austronesian languages, it is known for its subject-verb-object (SVO) word order.

Efforts have been made to promote and standardise the use of Filipino, which is based on Tagalog, as a means of fostering national unity and communication among the diverse linguistic groups in the Philippines. The language has evolved over the centuries, incorporating influences from various cultures, including Malay, Chinese, Spanish, and English, contributing to its unique linguistic characteristics.
