Life (noun) — the condition of being alive; also, the complete set of experiences and events that make up a person's existence. She leads a very active life in the city.
What Does Life Mean?
Life is one of the most fundamental words in English. At its most basic level it refers to the biological condition that separates living organisms from non-living matter — the state that makes plants grow, animals move, and people think and feel. In this sense it is the opposite of death.
Beyond biology, life is used to describe the full span of a person's experiences: their joys, struggles, relationships, and achievements. "She has had an interesting life" does not comment on her biology — it says her experiences have been varied and rich. This is the meaning most frequently encountered in everyday conversation and writing.
A third common use refers to a particular way of living or a specific sphere of activity: city life, working life, student life. Here life functions almost as a suffix, grouping related experiences together under a convenient label.
Etymology
The word comes from Old English lif, meaning "existence" or "the animate state", related to Old Norse líf and Old High German lib. All trace back to a Proto-Germanic root connected with the idea of remaining or continuing. The same root gives us the verb live, the adjective alive, and compound words such as lifetime, lifelong, and lifespan. The word has been in continuous recorded use since the earliest Old English manuscripts, more than a thousand years ago.

Usage Notes
Life is both countable and uncountable. When it refers to the general concept of being alive, it is uncountable and takes no article: "Life is unpredictable." When it refers to a specific person's or creature's existence, it is countable: "The rescue team saved three lives."
The plural lives (/laɪvz/) is irregular — not "lifes". This is also the third-person singular of the verb to live (/lɪvz/), but the pronunciation is different. Context normally makes the meaning clear: "She lives in London" (verb) versus "She has lived many different lives" (noun plural).
Note the distinction between life (noun) and live (verb or adjective). A frequent ESL error is writing "I love live" when the intended meaning is "I love life". Always check whether you need the noun or the verb.
