zirkuliert

Zirkuliert is the third-person singular present tense form of the German verb zirkulieren, which means to circulate or move in a continuous path within a closed system. The term is used for physical substances such as air or liquids, as well as for information, money, or signals that pass through networks or spaces. In everyday language it can describe anything that rotates or spreads through a given environment.

Etymology and related terms: Zirkulieren comes from the Latin circulare, via French circuler, with the German form emerging in the early modern period. Related noun forms include Zirkulation (circulation) and zirkulierend (circulating). The concept underpins disciplines ranging from physics and physiology to information science and economics.

Usage and contexts: In science, one speaks of die Luft zirkuliert im Raum (the air circulates in the room) or das Blut zirkuliert im Körper (the blood circulates in the body). In information or logistics contexts, eine Nachricht zirkuliert im Unternehmen (a message circulates within the company) or Geld zirkuliert im Wirtschaftskreislauf (money circulates in the economic cycle). The expression often conveys passage through a system rather than physical movement alone.

Grammar and forms: Zirkulieren is a regular verb. Present tense forms include ich zirkuliere, du zirkulierst, er/sie/es zirkuliert, wir zirkulieren, ihr zirkuliert, sie/Sie zirkulieren. The past tense is zirkulierte; the perfect uses haben, as in die Luft hat zirkuliert. Participle II is zirkuliert, and the present participle is zirkulierend.
