Pronunciation

  • UK: /ˈfɜːtəlaɪzə/[1]
  • US: /ˈfɜːɹtəlaɪzəɹ/[1]

Etymology

It is formed from English fertilize + -er.[2][3][4][5] The verb fertilize is formed from English fertile + -ize,[2][3][5] perhaps after French fertiliser;[6][3] the OED compares the French verb (1558), fertilizar (1454) and fertilizzare.[2] Fertile is from Middle French fertil and directly from Latin fertilis (“bearing in abundance, fruitful”),[4][2][7] from ferō (“to bear, carry”),[4][7] from Proto-Indo-European *bher- (“to carry; to bear children”).[4][7]

Earliest recorded meaning

Something that makes land fertile: before 1661, in Fuller's History of the Worthies of England (1662).[2][8] Hendrickson quotes the passage: sainfoin, or "Holy-hay", is "a great Fertilizer of Barren-ground".[8]

Semantic evolution

The agent noun followed the verb fertilize, recorded from 1610 in the OED,[2] from 1621 in Merriam-Webster[6] and in the 1640s in Etymonline.[4] At first a fertilizer could be a person or any agent that enriched the soil, also figuratively; that use is now rare.[2] From 1681, in Worlidge's Systema Agriculturæ, the word meant the substance itself, manure, compost or a chemical preparation,[2] and Etymonline notes it as a polite word for manure from 1846.[4][9] In 19th-century botany, from 1844 in a letter of Darwin, it also meant an insect or other agent that pollinates a plant;[2][3] the OED marks this obsolete after 1888,[2] but Collins still gives an organism that fertilizes an animal or plant.[10]
