BG

Bg is an abbreviation with multiple meanings across geography, language, computing, and everyday usage.

Geographic and political usage: BG is the ISO 3166-1 alpha-2 country code for Bulgaria. It is used in international commerce, vehicle registration, and the .bg internet country domain. Bulgaria’s capital is Sofia, and the official language is Bulgarian, which has the language code "bg" in many tagging systems.

Language coding: The two-letter code "bg" is the ISO 639-1 designation for the Bulgarian language. It appears in language identifiers, locale settings, and multilingual content tagging.

Computing usage: In Unix-like operating systems, the command "bg" resumes a suspended job and runs it in the background, enabling continued work in the shell. This pairs with the "fg" command, which brings a backgrounded or suspended job to the foreground.

Other common usages: In graphic design, web development, and digital interfaces, "bg" is commonly used as an abbreviation for background, as in "bg color" or "bg image" in CSS, HTML, and design notes. It may also appear in labels, diagrams, or shorthand notes referring to the background layer.

Disambiguation: Because "Bg" or "BG" can refer to different concepts depending on context, clarifying the domain—geography, language, computing, or design—helps determine the intended meaning.
