The acronym SEAL in the United States Navy SEALs stands for Sea, Air, and Land. It is derived from the teams' ability to operate on the seas, in the air, and on land.
The seal on a container or opening is the part where it has been sealed. When assembling the pie, wet the edges where the two crusts join, to form a seal. A seal is a device or a piece of material, for example in a machine, which closes an opening tightly so that air, liquid, or other substances cannot get in or out.
