fertile

Etymology

It is inherited from Middle English fertil, also fertyle,^[2][3] partly borrowed from Middle French fertil (“fruitful, producing abundantly”) and partly borrowed from Latin fertilis (“fruitful, productive”),^[4][2][3][5] from ferō (“to bear, carry”),^[4][2][6] from Proto-Indo-European *bʰer- (“to carry; to bear children”).^[2][6] The Latin adjective is based on the original past participle of the verb, *fertus,^[7][8] with the suffix -tilis, an extension of -ilis after adjectives such as fictilis and textilis.^[4] The French word was used of soil from the 14th century and of the mind from about 1450.^[4] Related forms are Old Occitan fertil, Spanish fértil, Portuguese fértil and Italian fertile.^[4] It is related to bear.^[7][9]

Earliest recorded meaning

Of land, suitable for growing crops and producing them in abundance, and of a plant, producing fruit or seed: both about 1440, in a translation of Palladius on husbandry.^[4] Barnhart dates the form fertyle to 1436,^[3] and Etymonline to the mid-15th century.^[2]

Semantic evolution

The sense moved from fields and plants to living beings and then to the mind.^[4] From 1481, in Caxton, it was used figuratively of whatever is rich in something or favours its growth,^[4] and since 1558 of people and animals, first meaning prolific and later simply able to have offspring.^[4][10] From 1621 a fertile mind or imagination was inventive.^[4][5] Johnson (1755) gave "fruitful; abundant; plenteous" as the first sense, quoting Shakespeare's "fertile England".^[11] Later senses are scientific: an egg or seed able to develop (1634), the time of life or of the cycle in which conception is possible (1878), and in nuclear physics a material that can be turned into a fissile one (1947).^[4][12] The OED notes that fertile also often translates French fécond and Latin fecundus.^[4] The Fertile Crescent was named in 1914 by the American archaeologist James H. Breasted.^[2]
