Forms
sien (feminine sienne, masculine plural siens, feminine plural siennes)[1] Old French suon, soen, suen, plural and subject suens.[2][3][4] Old French feminine soue, soie, seie, and in Picard sieue.[2][4]
Etymology
It is inherited from Old French suen, inherited from Latin suus (“his, her, their own”), through its stressed accusative ⟨suum⟩.[2][3][5][4][6] The TLFi traces ⟨suum⟩ to the Old French form by a differentiation of the two vowels, then diphthongisation and loss of the final ⟨u⟩.[4] The form with ⟨ie⟩ (about 1165) was remade after mien.[2][5][4]
The feminine is analogical too: it replaced Old French soue, from the stressed accusative ⟨suam⟩, with the variants soie (about 1180), formed after moie, and seie (1214).[2][3][4] The Picard sieue followed mieue.[4] Rey traces the Latin word to an Indo-European root Proto-Indo-European *swe- marking that a person belongs to a group or stands apart, also seen, extended, in Ancient Greek ἔθος (éthos, “custom”) and ἔθνος (éthnos, “people”).[2]
Earliest recorded meaning
The oldest record is the oblique feminine suo in the Strasbourg Oaths (842), in de suo part “on his part”.[4][5][3] The Sequence of St Eulalia (881) has Par souue clementia “by his mercy”.[4]
Semantic evolution
As an adjective beside a noun, “his, her own”, the word has been literary since the late 12th century.[2][5] Old French also used it on its own, as in maugré suen “against his will” (1176, Chrétien de Troyes).[4] As a noun, le sien meant “his property” (1130), a sense now kept only in y mettre du sien (1696) “to do one's part, show goodwill”.[2] The plural les siens (about 1240) means one's family, friends or supporters, and faire des siennes (1558) “to play one's usual tricks”.[2] The pronoun of possession le sien is found in Boileau in 1669.[2]
