fourth-round

The compound "fourth-round" is a modern English formation that logically combines two established concepts. "Fourth" originates from the Proto-Germanic 'fedworþô', derived from the cardinal number 'fedwōr' (four), and signifies the position following the third. "Round" evolved from the Latin 'rotundus', meaning circular or spherical, which in Old French took on the sense of a completed cycle or circuit. In the context of tournaments, this evolved metaphorically to mean a distinct stage where a set of contests is completed, creating a closed circle of competition. Thus, "fourth-round" literally denotes the fourth distinct stage in a sequential, often eliminatory, process.

Structure: fourth (number) + round (stage) - fourth: From Old English 'feowertha', related to 'feower' (four). A cardinal number suffix indicating ordinal position. - round: From Old French 'rond', from Latin 'rotundus' (circular). In this context, it denotes a stage or phase in a sequence, especially in competitions.
