buGÜN

Bugün is a Turkish adverb meaning "today." It denotes the present day and is used to refer to events or actions that occur on the current day. The word can also function as a temporal noun in contexts that treat "today" as a concept. In standard Turkish, bugün is written as a single word and is not declined; it can appear in compounds such as bugünkü, meaning "today's."

Etymology: The term is formed from bu ("this") and gün ("day"), literally translating to "this day." The two-component origin is common in Turkic languages; modern Turkish uses the closed form bugün. Some older texts or stylistic guides may show it as bu gün, but the single-word form is now standard.

Variants and usage notes: The simple form bugün is used in everyday language, including news reporting and conversation. It can appear in derivatives such as bugünkü ("today's") and bugünün ("of today" in possessive constructions). Example: Bugün hava sıcak. Bugünkü toplantı saat 14:00'te başlıyor. It contrasts with yarın ("tomorrow") and dün ("yesterday").
