öörahetus
Öörahetus is an Estonian term that appears mainly in regional dialects and historical sources, and there is no single universally accepted definition. Broadly, the word is associated with something nocturnal—a activity, duty, or vigil performed at night. In practical use, öörahetus has been described as an overnight handover or night-duty arrangement, where a person takes over responsibilities during the night after a daytime shift. In caregiving, security, and farming contexts, the term has been used to denote a night-time duty performed to maintain continuous operation or safety. In some texts it may also refer to the act of keeping watch or observing during the night.
