Pronunciation

Forms

mucos m or n (feminine singular mucoasă, masculine plural mucoși, feminine/neuter plural mucoase)[1]

Etymology

It is formed from Romanian muc + -os, as DEX, MDA2, the DLR and Tiktin give it.[2][3][4][5] Candrea–Densusianu and Pușcariu took it instead from Latin muccōsus (“snotty”), and Ciorănescu agrees that it may continue the Latin word;[6][7][1] Wiktionary gives both views.[6][7][1] muc is from Latin mūcus (“mucus, snot”).[7][1]

The word survives as Megleno-Romanian mucos.[8][7] The Latin adjective lives on in Catalan mocós, Spanish mocoso, Portuguese moncoso and Sardinian mukkozu.[7][6] The medical senses follow French muqueux, and the noun mucoasă “mucous membrane” was formed after muqueuse.[9][5][7]

Earliest recorded meaning

The first record is the Romanian–Latin glossary known as the Anonymus Caransebesiensis, which Tiktin dates to about 1670 and MDA2 to 1650–1700.[5][3] Klein's dictionary (1801) glosses it Latin mucosus.[10]

Semantic evolution

“With a runny nose” is the base sense,[2] which gave the scornful name for a cheeky youngster who gives himself grown-up airs, frequent in 19th-century prose: Ispirescu's „un mucos ca tine” “a snotty-nose like you”.[4][5][2] Regionally it is said of horses with glanders.[4] In the 19th century anatomy and medicine gave it the senses “secreting mucus” and “slimy”, after French muqueux; a text of 1831 speaks of the mucous surfaces of the digestive organs.[4][9] Eminescu applies it to a candle with a long, smoking wick: „mucoasa lumânare”.[11][5]
