fructose

Etymology

It was coined from Latin frūctus (“fruit”)^{[2][3][4][5][6]} with the chemical suffix -ose, used in the names of sugars.^[2][3][4][7] Merriam-Webster treats it as a word of the International Scientific Vocabulary, formed from a combining form of the Latin word.^[7] The OED, revised in 2018, says the word was apparently coined by the chemist W. A. Miller, and compares German Fructose, recorded from 1858 or earlier and now usually spelled Fruktose.^[2] The Latin noun meant "enjoyment" as well as "fruit, produce", and comes from the stem of fruor (“to use, enjoy”);^[3][5] it is also the source of fruit.^[3][8]

Earliest recorded meaning

A crystalline sugar found in fruit juices and honey: 1857, in W. A. Miller's Elements of Chemistry.^[2] Etymonline also dates it to 1857,^[3] while the 1989 edition of the OED, Barnhart and Merriam-Webster give 1864.^[9][4][7]

Semantic evolution

The word has kept its chemical sense.^[9][2] The 1989 edition of the OED defined it as fruit sugar or levulose, and noted that the name was also applied to the sugar found in fruit, which is a mixture of levulose and other sugars in varying proportions.^[9] The revised OED and Merriam-Webster define it more exactly, as one of the forms of this hexose sugar, especially the laevorotatory form that occurs in fruit juices and honey.^[2][7]
