Usage

Plural word for walrus The plural form of walrus is walruses.  The plurals of several other singular words ending in -us are also formed in this way, such as virus/viruses, sinus/sinuses, and syllabus/syllabuses. In some words derived from Latin that end in -us, the irregular plural ending -i may be used instead, as in fungus/fungi and cactus/cacti. However, this ending is not valid for walrus. Walri would be an invalid plural form for walrus.

Explanation

A walrus is a large mammal that lives in the sea and has big flippers and very long tusks. If you'd like to keep a walrus for a pet, you'll need a big pool full of salt water and plenty of clams, a walrus's favorite snack. Walruses are very distinctive, both for their tusks and whiskers and their size: some male walruses weigh over 2,000 pounds. They are extremely important in Arctic indigenous culture and are referenced frequently in Western culture as well. A couple of famous examples are Lewis Carroll's oyster-eating walrus in "The Walrus and the Carpenter." and the mysterious reference in the Beatles' "I Am the Walrus."
