Säänö

Sání is a Czech noun that denotes the act of sucking or drawing a liquid, gas, or other substance into something by means of suction. It is derived from the verb sát, with the nominal suffix -ní. The term appears in both everyday language and technical contexts, and it can refer to a variety of suction-related processes.

In biology and everyday life, sání most commonly describes the act of nursing an infant or the general act of sucking on a nipple, pacifier, or other object. It is also used in medical settings to describe suctioning fluids from a body cavity or wound, performed with specialised devices.

In engineering and technology, sání denotes the intake portion of a system, most notably the air intake of an internal combustion engine (sání vzduchu). Efficient sání is important for performance and efficiency, and design often addresses the path, filtration, and flow dynamics of the intake.

Related terms include odsávání, which more precisely means suction or aspiration, and sání vzduchu as a fixed phrase. The concept covers both natural acts, like feeding, and technical systems that move fluids or gases by suction.
