Seal
Seal (animal)
A sea animal with flippers that lives on cold coasts.
On the nature show, a seal slid off the ice into the sea.
Seal (close tightly)
To close something so nothing can get in or out.
Amma sealed the pickle jar tightly with its lid.
Remember: A seal swims; you seal a jar. The animal word and the closing word came from different old words.
