Etymology and origin of the Italian word stagno
stagno1 tin
From the same root · stagno1
Pronunciation
- /ˈstaɲ.ɲo/[1]
Forms
stagno m (plural stagni); as an adjective, feminine stagna, masculine plural stagni, feminine plural stagne[1] Old forms include Old Italian staino, recorded at Perugia in 1379, and Old Italian stagnio.[2][3]
Etymology
The word for the metal is inherited from Latin stagnum (“alloy of silver and lead; tin”), also spelled stannum.[4][5][6][1] The Latin word first named an alloy of lead and silver and came to mean “tin” in imperial times, when the metal was imported from north-western Spain and the British Isles.[5][7] DEI adds that for Pliny it was an alloy said to be a Celtic invention, while tin itself was plumbum album, “white lead”.[2] The same word is French étain, Occitan estanh, Catalan estany, Spanish estaño and Portuguese estanho.[5][8]
Most sources take the Latin word to be of Gaulish origin.[4][6][9][10] DEI explains it from Insular Celtic, comparing Welsh ystaen and Breton sten, and Wiktionary derives it from Proto-Celtic *stagnom, comparing Irish stán.[2][1] Nocentini calls it a loan from an unknown source.[5] R. Halleux, cited by DELI, takes it instead as a derivative of the Latin word for a pond, through stagnō in the senses “to form a stagnant layer” and “to be covered with such a layer”; the GDLI reports this view too.[4][3]
The adjective “watertight” is the shortened past participle, without a suffix, of stagnare in its sense “to coat with tin; to seal”, a verb formed on this word.[5][11][12][3] Wiktionary files it instead under the word for the pond.[1]
Earliest recorded meaning
The first record is in Guittone d'Arezzo, before 1294, for the metal.[4][6] Zingarelli dates the word to 1282.[9]
Semantic evolution
Medieval Latin at Venice had instagnare “to tin” in 1271, and Italian stagnare appears in a statute of the Sienese locksmiths' guild (1323–1402).[4] The craftsman who tins and mends pots is stagnaro in Mattioli in 1544 and stagnaio in a Florentine register in 1552;[4] Migliorini cites stagnino, stagnaio and stagnaro as regional synonyms for the same trade.[4] Stagnola, tin foil, and stagnino are recorded from 1873.[5]
The adjective “watertight” dates from the 16th century.[5][11] DEI records it at Arbe in the 16th century with the sense “waterproof”, and in the northern dialects with the sense “solid”.[2] It is mainly a nautical word: compartimenti stagni are the sealed sections of a hull, and figuratively, parts of an organisation that do not communicate.[11][12]

stagno2 pond
From the same root · stagno2
Pronunciation
- /ˈstaɲ.ɲo/[1]
Forms
stagno m (plural stagni)[1]
Etymology
The word for the pond is inherited from Latin stāgnum (“standing water, pool”).[4][5][6][1] The Latin word is found from Ennius on, with the imperial derivative stagnō (“to form a pool; to stagnate”).[2][14] The same word is Occitan estanh and Catalan estany, and Engadine stagn.[5][8]
Its origin is uncertain, and Nocentini finds no sure comparison.[4][5] De Vaan reports a root Proto-Indo-European *steh₂g- (“to seep, drip”), put forward with hesitation for this word and for Ancient Greek στάζω (stázō, “to let drip”), but finds no matching formations;[14][1] Wiktionary also mentions τέναγος (ténagos, “shallows”).[14][1]
The literary adjective “still, stagnant” is the shortened past participle of stagnare “to stagnate”.[3]
Earliest recorded meaning
The first record is the form estagno in the 13th-century Compasso da navigare, a sailing guide;[4][6] stagno appears in the Italian Crescenzi of about 1350.[4][6]
Semantic evolution
DEI records the word as a Tuscan place name from 1128, also in the derivative Stagneto.[2] The verb stagnare is in Dante: Come ad Arli, ove Rodano stagna (“As at Arles, where the Rhône forms a marsh”).[3][11] Petrarch has stagnante (before 1374), the Italian Crescenzi uses stagnare for stopping the flow of blood (about 1350), and in 1965 the verb was applied to a stagnant economy.[4] Ristagnare (14th century) and stagnazione (18th century) belong to the same group.[5]
Old poets used the adjective stagno for “motionless”, and Montale for air heavy with stagnant heat (all'afa stagna).[3]
