Pronunciation

  • /ˈliːflɪt/[1]

Etymology

It is a diminutive formed from English leaf + -let.[2][3][4][5] Klein notes that it joins a native word to a suffix of French origin.[6] In its botanical senses it followed the scientific use of New Latin foliolum (English foliole).[2]

Earliest recorded meaning

In botany, each of the small leaves into which a compound leaf is divided: 1777, in William Curtis's Flora Londinensis.[2] Merriam-Webster dates the word to 1785,[7] Etymonline to 1787.[3]

Semantic evolution

The botanical sense came first; in 1785 the word was also used for a segment of a calyx, a sepal.[2][4] From 1793 it meant any small or young leaf,[2] From 1826 it was used in zoology for a thin, leaflike structure such as a gill filament; from 1873 it was used of the flaps of a valve in the heart or a vein.[2] The printing sense arose in the mid-19th century: a literary leaflet (1852–67) was a short article in a periodical.[2] From 1860 a leaflet was a single printed sheet, folded or not, handed out free, with advertising or political information.[2][3] The verb, to hand out leaflets, dates from 1962.[2][7]
