seal
/siːl/
The word carries a strong sense of permanence and security. Whether referring to a physical airtight closure or a legal stamp, it suggests a state of being locked, finalized, or protected from outside interference. When used in social or professional contexts, it shifts from a physical action to a symbolic one. To seal a deal is not about physical barriers but about reaching a point of no return in a negotiation, creating a psychological bond of commitment.
Countable when referring to the animal or a specific physical object like a wax stamp. Uncountable when referring to the general state of being sealed or the substance used as a sealant.

Etymology
The word derives from two distinct roots. The animal sense comes from the Old English "seolh," originating from a Proto-Germanic root meaning seal. The sense related to closing or authenticating comes from the Old French "seel," which evolved from the Latin "sigillum," a diminutive of "signum," meaning a sign or mark.
