four-team

The compound adjective "four-team" is a modern, transparent formation built from two ancient English roots. "Four" descends from the Proto-Indo-European numeral kʷetwóres, which entered Germanic as fedwōr and became the Old English fēower. "Team" has a more specialized journey, originating from the Proto-Germanic taumaz meaning 'that which pulls or draws', which in Old English narrowed to tēam, referring initially to offspring and later to a set of draft animals harnessed together. The conceptual shift from a literal line of beasts to a cooperative human group occurred in Middle English. The logic of the compound is purely arithmetic and descriptive, directly combining the quantity "four" with the collective unit "team" to specify a structure or competition involving four distinct groups.

Structure: four (number) + team (group) - four: From Old English fēower, of Proto-Germanic origin; related to Dutch vier and German vier, from an Indo-European root shared by Latin quattuor and Greek tessares. Functions as a numerical quantifier. - team: From Old English tēam 'childbearing, offspring, family', of Germanic origin; related to German Zaum 'bridle' and Dutch toom. The sense evolved via 'line of draft animals' to 'group working together'. Functions as the core noun denoting a group.
