The formal definition of a latch spans multiple distinct fields, encompassing mechanical hardware, infant feeding, and electronic engineering. In mechanics and construction, a latch is defined as a mechanical fastening device used to secure a door, gate, window, or box lid without utilizing a full key-operated lock, relying instead on a spring-loaded or sliding bolt. In biological and lactation terminology, a latch represents the physical attachment and suction seal formed by an infant's mouth onto a mother's breast for feeding. In digital electronics, a latch is defined as a memory circuit that stores a single bit of binary information until triggered to change states by input signals.

Formally defined, a latch functions as both a noun and a verb. As a noun, it refers to a mechanical fastening device used to secure a door, gate, or cabinet panel, holding it closed without requiring a key-operated lock or deadbolt mechanism. As a verb, it means to fasten, close, or attach something securely together. In infant care and lactation, to latch means for a newborn to attach properly to a mother's breast for feeding. In electronics and digital computing, a latch describes a logic circuit used to store a bit of data. You can verify these definitions through standard English dictionary references.
