morphine

Etymology

It is borrowed from French morphine,^[2][3][4] formed from Morphée, the French form of the name of Morpheus, and the suffix -ine, after German Morphium.^[2] The OED records the French word in 1817 and Morphin in 1818, and takes the English spelling morphin as probably directly from the German;^[2] Etymonline and Barnhart give French morphine or German Morphin as the source,^[5][6] and Dictionary.com and the Oxford Dictionary of English the German word alone.^[7][8] Etymonline dates Morphin to 1816 and says it was coined by the German apothecary Friedrich Sertürner.^[5] The name alludes to Morpheus, the god of dreams, because the drug brings sleep.^[6][5][9] According to Barnhart the name was coined by Ovid from Ancient Greek μορφή (morphḗ, “form, shape”), with reference to the forms seen in dreams;^[6][5] Etymonline calls the Greek noun of unknown origin.^[5] Klein cites the god's name as Ancient Greek Μορφεύς (Morpheús).^[9]

Earliest recorded meaning

The chief alkaloid of opium: 1817, in the Quarterly Journal of Science & Arts,^[2] a date the Merriam-Webster Unabridged shares;^[4] Etymonline and Barnhart give 1828.^[5][6]

Semantic evolution

The word has kept its single chemical sense.^[2] It replaced the earlier New Latin name morphia, recorded from 1818 and likewise formed from the name of Morpheus,^[6] which Collins still lists as an alternative.^[10] The Shorter Oxford records morphinated, containing morphine, and the rare morphined, drugged with morphine, from the late 19th century.^[11]
