Forms

sinistra f (plural sinistre)[1] An old form is sinestra.[2][3]

Etymology

It is the feminine of the adjective sinistro (“left”) used as a noun, short for the phrases meaning “left hand” and “left side”.[4][5][6][7] The adjective is inherited from Latin sinister (“left”), and Latin already used the feminine sinistra as a noun for “the left hand, the left”.[8][9][1] Wiktionary treats the noun as inherited directly from Latin.[1] The adjective survives in Old Italian sinestro, Old French senestre, Old Occitan senestre and Spanish siniestro.[10][11] Forms with ⟨e⟩ such as this one were remodelled after dexter (“right”).[10]

De Vaan holds that the sense “left” was a later development in Latin, beside the older laevus and scaevus: the word may be a comparative of a root Proto-Indo-European *senh₂- (“to gain”), “the more favourable side”, a euphemism, but he finds the meaning too vague to be sure.[9][1]

Earliest recorded meaning

GRADIT dates the noun to the end of the 13th century, and DEI records the old form sinestra in the 13th century.[6][3] DELI's first record is in Dante, before 1321, for the left hand: in the Inferno the angel clears the thick air from his face menando la sinistra innanzi spesso (“often moving his left hand before him”).[4][12]

Semantic evolution

From the hand the word passed to the side or direction on the left, and at sea to the left side of a ship (1786–1803).[4] The political sense comes from the French Revolution, when the progressive deputies sat to the left of the president of the assembly; in Italian it is recorded in a popular political dictionary of 1851.[4][8]

The adjective sinistro kept the Latin sense “unfavourable, ill-omened”, but the noun did not.[8] Derivatives of the political sense include sinistrismo, sinistroide and sinistrese, the jargon of the left.[6][1]
