Birden

Birden is a Turkish adverb meaning "suddenly" or "all at once." It signals that an action or situation occurs quickly and unexpectedly. In sentences, it is typically placed before the verb it modifies: "Birden çıktı" meaning "He/She suddenly left." It can also introduce a rapid change or onset, as in "Birden sessizlik oldu" meaning "There was sudden silence," or describe a shift in a story's pace.

Grammatical notes: Birden is invariable; it does not inflect for person, number, or tense. Its meaning is preserved across contexts, and it combines with verbs in all tenses to express immediacy. In everyday Turkish, birden is common in both spoken and written language and is used to convey a sense of abruptness without specifying cause.
