Borrowed from Latin lēns (“lentil”); Medieval Latin later taking on the sense of "lens"; a semantic loan from Arabic عَدْسَة (ʕadsa, “lentil; optic lens”).
lens (plural lenses or (obsolete) lens or (rare) lentes)
- An object, usually made of glass, that focuses or defocuses the light that passes through it.
- 2013 July-August, Catherine Clabby, “Focus on Everything”, in American Scientist:
- Not long ago, it was difficult to produce photographs of tiny creatures with every part in focus. That’s because the lenses that are excellent at magnifying tiny subjects produce a narrow depth of field.
- A device which focuses or defocuses electron beams.
- (geometry) A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune.
- (biology) A genus of the legume family; its bean.
- (anatomy) The transparent crystalline structure in the eye.
- 2013 July-August, Fenella Saunders, “Tiny Lenses See the Big Picture”, in American Scientist:
- The single-imaging optic of the mammalian eye offers some distinct visual advantages. Such lenses can take in photons from a wide range of angles, increasing light sensitivity. They also have high spatial resolution, resolving incoming images in minute detail.
- (earth science) A body of rock, ice, or water shaped like a convex lens.
- (programming) A construct used in statically-typed functional programming languages to access nested data structures.
- (by extension, figuratively) A way of looking, literally or figuratively, at something.
- 2004 April 11, Ann Hulbert, “Are the Kids All Right?”, in The New York Times Magazine, page 11:
- If "the public looks at the condition of America's children largely through a negative lens," worries Child Trends […] , "it may be more difficult to […] promote child well-being."

lens (third-person singular simple present lenses, present participle lensing, simple past and past participle lensed)
- (transitive, cinematography) To film, shoot.
- 2020 May 7, Katie Rife, “If you’re looking to jump in your seat, make a playdate with Z”, in The Onion AV Club:
- It’s set in an anonymous, upper-middle-class suburb, lensed in the generic gunmetal gray that will one day appear as dated as the fuzzy outlines of ’80s direct-to-video horror movies.
- (geology) To become thinner towards the edges.
From Dutch lens, from Latin lēns (“lentil”).
lens (plural lense)
Borrowed from Latin lēns (“lentil”).
lens f (plural lenzen, diminutive lensje n)
Probably related to lans (“lance”).
lens m (plural lenzen, diminutive lensje n)
- (historical) A type of barbless harpoon used for killing whales.
From Middle Dutch lense, of uncertain origin. Perhaps a variant of Middle Dutch lunse (see luns), or perhaps a dialectal borrowing from Old Frisian *lens, *lenis, from Proto-West Germanic *lunis, related to Old English lynis (“linchpin”).
lens f (plural lenzen, diminutive lensje n)
- Alternative form of luns
lens (comparative lenzer, superlative meest lens or lenst)
|Inflection of lens|
- Petjo: lens
Unknown, likely a borrowing from an unidentified source.
Compare Old High German linsa, Lithuanian lęšis, Old Church Slavonic лѧща (lęšta), and Albanian lend (Proto-Albanian *lenta), sounding too similar for a coincidence, however different enough to prohibit reconstruction of a common PIE protoform. May also be related to Ancient Greek λάθυρος (láthuros).
If ultimately a non-IE substrate loanword, locating the source is virtually impossible because cultivation of lentil was widespread in the region since the Neolithic.
lēns f (genitive lentis); third declension
Third-declension noun (i-stem, accusative singular in -em or -im, ablative singular in -e or -ī).
- Aromanian: linti

- → English: lens
- Friulian: lint
- → Galician: lente
- → Italian: lente
- → Portuguese: lente
- Romanian: linte

Unknown. According to de Vaan, perhaps a deformed form of what is found as Proto-Slavic *gňìda (“nit”), Proto-Germanic *hnits (“nit”), Ancient Greek κονίς (konís) (gen. κονίδος (konídos)), Armenian անիծ (anic, “nit”); he proposes Proto-Indo-European *dḱ(o)nid- > *dkni-n-d- > *dklind- > Proto-Italic *(d)lind-. However, like the Indo-European cognates, it may be of substrate origin.
lēns f (genitive lendis); third declension
- Late Latin: lendis (see there for further descendants)
