tungkol

Tungkol is a Filipino word meaning "about" or "concerning." It functions as a preposition or modifier that links a statement, passage, or discussion to its topic. In most uses, it appears together with the preposition sa to form the phrase tungkol sa, which introduces what the text is about. For example: Ang ulat ay tungkol sa kalusugan. Mayroong debate tungkol sa ekonomiya. Tungkol sa kalikasan ang pahayag. Both orders are acceptable in everyday Filipino, though the standard form places the topic after the subject.

A related form, patungkol, is more formal or literary and carries the same meaning as tungkol sa. It is commonly found in official statements and legal writing: Patungkol sa bagong batas ang pahayag. In writing and speech, tungkol is widely used to set the topic, summarize content, or introduce discussions, essays, news reports, and presentations. It is one of the core particles that helps structure information in Filipino.
