Origin & History of “third”

Third goes back ultimately to an Indo-European *tritjos, an ordinal derivative of the base that produced English three. Amongst its other descendants were Greek trítos, Latin tertius (source of English tertiary (16th c.)), Russian tretij, polish trzeci, Latvian trešais, and Welsh tryddydd. In prehistoric Germanic it became *thrithjaz, which has evolved into German dritte, Dutch derde, Swedish and Danish tredje, and English third.
