Pronunciation

Etymology

It is formed from English thumb + nail.[2][3][4][5]

Earliest recorded meaning

The nail of the thumb: 1604, in Dekker and Middleton's The Honest Whore.[2][4] Etymonline gives about 1600.[3]

Semantic evolution

In 1852 a thumb-nail sketch was a drawing about the size of a thumbnail, and then, figuratively, a brief description in words;[2][3] Etymonline notes that thumbnail alone, short for the phrase, is recorded by 1901, usually without the literal size.[3] In printing a thumbnail was a miniature version of a document from 1933,[2] and in computing it became a small version of a digital image, often linked to the full-size one.[2][4][6] The verb, to describe in a thumbnail sketch, is recorded from 1932.[2][4]

Timeline

  • 1604 – the nail of the thumb.[2][4]
  • 1852 – thumb-nail sketch, a very small drawing; a brief description.[2][3]
