What’s the plural of “life”?
A cat has nine lives.
She lives in the city center.
They risked their own live to save others.
The book describes the interesting lives of the protagonist.
Life is a noun, and the correct plural is lives. Lives can also be a verb, which can be literally understood as the act of living this so-called life. Lives is also the third-person singular form of live. This admittedly sounds confusing, but it’s really not. The difference is in the parts of speech both words belong to, and their pronunciation.
Life refers to the state of existence (or being alive), or the period between birth and death. This is how the noun form of life, which sounds like lyfe, is used. The verb form of life is live (which sounds like liv as in olive). Lives is the plural of the singular noun life, but lives is also how you can refer to the third-person singular of the verb live. The correct context in which you should use the verb form vs. the noun form of lives is clear in practice and speech. See these sentences:
He lives on third street.
A cat has nine lives.
See the difference? Lives as a noun refers to multiple lives in a literal sense. Lives in the third-person singular mentions a specific person that is actually performing the action of the verb live.
Lifes or lives?
Lifes is incorrect, and is not a recognized word in English. But, were it to appear, it should include an apostrophe, i.e., life’s. This shows that it’s either a possessive noun or contracted form of life + is. Here’s the difference:
Her life’s goal is to become a famous novelist.
Life’s too short to spend doing what you don’t love.
What’s the definition of life?
The online dictionary defines a life as:
The condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally

They’re basic, easy plurals; all you have to do is attach the s.

Lives is not alone in its cohort of irregularity, as will be shown in the section below.
“life’s” plural, associate “lives” with the verb “live”—they sound alike and both relate to the state of being alive.

Origin of the word life
Each of these words, unsurprisingly, share etymology and place of origin. Each came was down to Modern English from the Germanic languages, or PIE (Proto-Indo-European region.) Students of Germanic languages and linguistics are likely familiar with the i-umlaut (a particular favourite on the #GFlex blog.)
The i-umlaut, (which is another Germanic way to denote a plural that involves exchanging vowels from sing. to pl. forms) is responsible for the irregular plurals such goose goes to geese; foot to feet, tooth to teeth (but not moose, that stays as moose—it comes from the Algonquian languages.) The i-umlaut describes one method Germanic languages used to denote a plural. Here, the rule that applies in the case of singular nouns that end in -f/-fe (sometimes referred to as a sibilants: wolf, knife, wife, life, etc. Each ends in –ves as a plural noun, replacing the sibilant -f/-fe in the singular case.
