life
Old English
“The oldest English word for existence once meant just the living body.”
Old English 'līf' named the body before it named existence itself. The word appears in Beowulf, composed between 700 and 1000 CE, where 'lif' names both what a warrior has and what he can lose. Its Proto-Germanic ancestor lībą carried a sense of clinging or adhering, as life clings to a person until it doesn't. The Old Norse cognate 'líf' meant both body and life, without any gap between the physical and the vital.
The Proto-Indo-European root leyp- meant to stick, smear, or adhere with something fatty. Latin 'lippus' (having inflamed, sticky eyes) shares this ancestry, as does the Greek 'aleiphein' (to anoint with oil). By the 10th century, Old English 'līf' had expanded beyond the physical body to encompass the whole span of a person's days on earth. The two meanings coexisted in the same word without apparent conflict for several centuries.
The King James Bible of 1611 forced 'life' to translate both the Greek 'zōē' (divine or eternal life) and 'bios' (mortal, biographical life). Greek theology had kept these concepts separate; English collapsed them into a single syllable. Translators working on John 10:10 chose 'life' for 'zōē', a word their English could barely contain. Samuel Johnson's 1755 Dictionary listed fifteen distinct senses of 'life', more than almost any other entry in the first edition.
Modern biology gave 'life' a new problem: defining it. NASA's working definition, 'a self-sustaining chemical system capable of Darwinian evolution', satisfies biochemists but leaves poets with nothing to work with. The word that once named a Northumbrian warrior's breathing body now carries the weight of astrobiology, philosophy of mind, and bioethics. Four letters, one syllable, and the subject of every argument that matters.

The word 'life' now performs so many tasks simultaneously that it has become almost impossible to define in a single sentence. It describes what a cell does, what a person has, what a biography records, what a sentence can be given, and what water is said to bring. Philosophers since Aristotle have tried to pin down what separates the living from the non-living, and the word has absorbed every attempt without losing its shape. That is the sign of a word that means something fundamental.
In ordinary speech, 'life' still carries its original bodily weight even when the speaker has something abstract in mind. 'Get a life' is a rebuke to the overly mental. 'For dear life' is a purely physical phrase, all grip and survival. The word's oldest meanings never left; they simply went quiet beneath newer ones. Old English had it right: life is first a body, and only then a concept.
