Yoke, on the other hand, applies only to two animals customarily yoked together: as, a yoke of oxen. Brace is rather a hunters' term, with limited and peculiar application: as, a brace of partridges, pistols, slugs. Dyad is used in philosophical and mathematical language only. Duad is a special mathematical word signifying an unordered pair.
