Forms
tun n (plural tunuri)[1] In the sense “thunder” old texts have the plurals tune and tunure: Varlaam writes „În tunure și în fulgere și în cutremur de pământ” “in thunders and lightnings and earthquake”.[2][3][4]
Etymology
The DLR, MDA2 and Graur take it as a back-formation from Romanian tuna (“to thunder”).[2][4][5] The verb is from Latin tonō (“to thunder”).[6][7] Ciorănescu and Tiktin give this view or the Latin noun discussed below.[6][3]
The DEX, Șăineanu, Scriban and Wiktionary derive it from Latin tonus, which is τόνος (tónos, “tension, tone”), with the sense “thunderclap” of its Romance cognates.[8][9][10][1] Tiktin compares Dalmatian tun and Italian tuono “thunder”.[3] Graur objects that the Latin noun survives in the Romance languages only as a learned loan;[5] Seneca found the noun with the sense “thunder” in a writer of the 1st century BC as an archaic word beside tonitrum, and Graur takes both the Latin word and the Romanian one as made separately from the verb.[5] ton “tone” is a doublet, borrowed through French.[1]
Earliest recorded meaning
The first record is in the Psaltirea Hurmuzaki, with the sense “thunder”: „De glasul tunrului tău spământă-se” “at the voice of thy thunder they were afraid” (Psalm 103).[4][2][3]
Semantic evolution
“Thunder” was the old sense, which survives in popular speech and in folk belief: the archangel Gabriel is said to carry the stone and rule the thunder.[2][3] When firearms came, the cannon was named after its noise;[3] Tiktin notes that the oldest cannons were called “thunder guns” in German.[3] Miron Costin plays on both senses in a saying: he who is meant to die by a cannonball dies by a thunderbolt.[3] The DLR quotes the cannon sense from the 17th-century chronicles on, and Klein's dictionary of 1801 still gives both senses.[2][11]
After a verb or an adjective tun became an intensifier: înghețat tun “frozen hard”, sănătos tun “hale and hearty”, doarme tun “sleeps like a log”, beat tun “dead drunk”.[3][8] Graur thinks înghețat tun came first and meant water frozen so hard that cannons could cross it, the other phrases being imitations of it.[5] In slang since the 1990s tun is a big illicit coup, a swindle that brings huge profits: a da un tun.[12][13]
