fa

Fa is a term with several distinct uses in music, language, and names. In Western musical pedagogy, fa is the fourth note of the diatonic scale in solfège. In movable-do systems, fa designates the fourth scale degree, while in fixed-do systems it corresponds to the actual pitch F.

fa is also the ISO 639-1 language code for Persian, typically rendered as Farsi or Persian. In academic and technology contexts, fa denotes the Persian language, including its writing system and literature.

Fa can function as a surname or given name. In Chinese, it is a transliteration of surnames written with characters such as 法, and speakers of Chinese may romanize those surnames as Fa. The form also appears as a given name or nickname in various cultures.

Beyond these uses, FA as an initialism appears in many domains, including Football Association, Financial Aid, and Free Agent, among others. The meaning is determined by context.
