+ '''sein''' ''m'' (plural seins)^(Wiktionary)
+ Old French ''sein'', ''sain''.^(TLFi)^(Littré 1873)
+
+ ==Etymology==
+ It is [[inh|fro|sein]], [[inh|la|sinus|t=curve, fold; fold of the toga across the chest; bosom; bay]].^(TLFi)^(DHLF 1992)^(Bloch & Wartburg 1989)^(Grand Robert 2005)^(FEW|11, 650b)^(Wiktionary) The fold of the toga, gathered over the shoulder, was where women carried their child, hence the Latin figurative sense “bosom, breast”; the word also meant “refuge” and, in phrases, “the inside of” ([[m|la|in sinū urbis|t=in the heart of the city]]).^(DHLF 1992)^(Petit Robert 2007) In Christian Latin the bosom of Abraham (Luke 16:22) and the bosom of the Church are [[m|la|sinus Abrahae]] and [[m|la|sinus ecclesiae]].^(TLFi) The Latin word has no known etymology.^(DHLF 1992)^(Petit Robert 2007) It is a doublet of the learned [[sinus]].^(Wiktionary)
+
+ Cognate with [[ro|sân]], [[it|seno]], [[oc|sen]], [[ca|si]], [[es|seno]] and [[pt|seio]].^(Petit Robert 2007)^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ Philippe de Thaon's ''Bestiaire'' (1121–34) uses it for the part of the garment covering the chest, the space between chest and clothing.^(TLFi)^(DHLF 1992)^(Grand Robert 2005) The same text has ''el sein saint Abraam'' “in the bosom of Abraham”.^(TLFi)
+
+ ==Semantic evolution==
+ From about 1150–60 it named the front of the human chest, often as the seat of feeling, the usual sense in the classical period when ''poitrine'' was rare.^(TLFi)^(DHLF 1992) Already about 1155–74 Wace speaks of the earth that fed him “in its bosom”, and ''au sein de'' “in the midst of” is in Du Bellay (1558).^(TLFi)^(DHLF 1992) From about 1200 ''sein'' meant a woman's chest, and in the 16th century each of her breasts (''ces femmes qui ont si grans sains'', early 16th century); the plural ''les seins'' became common only in the 19th century.^(TLFi)^(DHLF 1992) ''Donner le sein'' “to breastfeed” is recorded in 1802, and the word is used of the womb in literary language (1682).^(TLFi)
+
+ In the 16th century it took further Latin senses by learned borrowing: “gulf” (''le Sein Arabique'', 1534) and the belly of a sail (1564, ''sein d'une voile'', 1702).^(TLFi)^(DHLF 1992)
