Pronunciation

Forms

sân m (plural sâni)[1] In the sense “breast of a woman” the plural is sâni (masculine); in the other senses it is sânuri (neuter).[2] An older variant is sin.[3][2]

Etymology

It is inherited from Latin sinus (“fold, cavity, bosom”).[4][3][1][5] The word survives in all four branches: Aromanian sin, Megleno-Romanian sin and Istro-Romanian sir.[4][6][7][8] The Romance cognates include Italian seno, Spanish seno, French sein and Portuguese seio.[4][5]

De Vaan connects the Latin word, probably, with Albanian gji (“breast”), through a Proto-Albanian form with ⟨n⟩; he gives it no further etymology.[9]

Earliest recorded meaning

MDA2 dates the first record to the Psaltirea Hurmuzaki, written about 1500–1520.[3] The Codicele Voronețean uses the word for a bay of the sea, in the account of Paul's shipwreck (Acts 27:39).[10][11] Coresi's psalter of 1570 has sîn and sînul “bosom”.[12]

Semantic evolution

Ciorănescu explains that the peasant wears his shirt open and belted at the waist, so that its front serves as a pocket; hence phrases such as a umple sânul “to lay in provisions”.[4] From the chest the word passed to the breast of a woman, the womb, the heart as the seat of feeling and, figuratively, the inside or middle of something (sânul pământului “the bosom of the earth”).[2][10] The old sense “bay, gulf”, used in old geography books, is now obsolete.[11][2]

Many idioms are built on the word: a sta cu mâinile în sân “to sit idle”, a crește șarpele în sân “to nourish a viper in one's bosom” and a umbla cu crucea-n sân “to be devout”, or ironically “to be a hypocrite”.[3][2] În sânul lui Avram “in Abraham's bosom”, from the Gospel parable (Luke 16:22), means “happy, well off”.[10][2]
