Etymology

Borrowed from Latin l?ns ("lentil"), in Medieval Latin later taking on the sense of "lens".

Pronunciation

  • IPA(key): /l?nz/
  • (file)
  • Rhymes: -?nz

Noun

lens (plural lenses or (obsolete) lens)

  1. 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.
  2. A device which focuses or defocuses electron beams.
  3. (geometry) A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune.
  4. (biology) A genus of the legume family; its bean.
  5. (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.
  6. (earth science) A body of rock, ice, or water shaped like a convex lens.
  7. (programming) A construct used in statically-typed functional programming languages to access nested data structures.
  8. (by extension, figurative) 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."

Latin

Etymology 1

Unknown, likely a borrowing from an unidentified source.

Compare Old High German linsa, Lithuanian lis, Old Church Slavonic ? (lta), 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 ? (láthuros).

If ultimately a non-IE loanword, locating the source is virtually impossible because cultivation of lentil was widespread in the region since the Neolithic.

Pronunciation

Noun

l?ns f (genitive lentis); third declension

  1. lentil
  2. (Medieval Latin) lens
Declension

Third-declension noun (i-stem, accusative singular in -em or -im, ablative singular in -e or -?).

Etymology 2
