fz

Fz, or fz, is a two-letter combination that appears in a variety of contexts. It does not have a single, universal meaning; its interpretation depends on capitalization, industry, and surrounding text.

In popular culture, FZ is widely recognized as the initials of Frank Zappa (1940–1993), the American musician and composer known for his eclectic approach to rock, jazz, and experimental music. In biographical or discographic contexts, "FZ" may be used as shorthand to refer to him or his body of work.

In transportation, FZ is the IATA airline designator for Flydubai, a Dubai-based airline established in 2009. The code identifies the carrier in tickets, timetables, and aviation databases, and is used in flight numbers such as FZ123.

In technology and computing, fz or FZ can appear as an abbreviation, mnemonic, or command alias. Some users configure a shell script or alias named "fz" to invoke a particular tool, such as a fuzzy finder, or to stand in for a project-specific command. These uses are informal and vary by user and environment.

Other uses occur as model numbers, product codes, or internal identifiers across different industries. Because there is no single authoritative meaning, the intended sense of "fz" is typically inferred from context, capitalization, and accompanying terms.
