Forms
tiers (feminine tierce, masculine plural tiers, feminine plural tierces)[1] Old French feminine terce (about 980), masculine terz (late 11th century), tierz (about 1160), then tiers (13th century).[2][3][4]
Etymology
It is inherited from Old French tiers, inherited from Latin tertius (“third”), from ter (“three times”), itself from trēs (“three”).[5][2][4][1][6]
Cognate with Italian terzo, Old Occitan tertz, Catalan ters and Spanish tercio.[7][8][9]
Earliest recorded meaning
It is first found at the end of the 10th century in the Passion, in the forms terz and terce, meaning “third”: al terz di “on the third day”.[5][4]
Semantic evolution
As an adjective tiers meant “third” until the early 17th century, when troisième replaced it; it survives in fixed phrases such as tierce personne (1585), tiers ordre (tierce ordene, 1326) and tiers état (1376, again from 1576), shortened to le Tiers in 1675.[9][2][5] Fièvre tierce (1342) was used until the 19th century.[2] Law added tiers opposant (1585), tiers arbitre (1694) and tierce opposition (1762).[5]
As a noun, le tiers is the third part of a whole (1172–1174), and in law a third person besides the two parties (early 12th century), hence any outsider (1246) and être en tiers (1676).[2] Le tiers et le quart “anybody at all” dates from 1399, and gave se moquer du tiers comme du quart.[2][5] In the 20th century, when the word seemed to have lost its vitality, tiers monde was coined after tiers état.[2]
