Contrast this with Set 2, the family (home to Arabic, Hebrew, and Amharic). Here, the engineer’s focus shifts from the noun to the verb. This family is famous for its non-concatenative morphology . While Niger-Congo builds words by snapping bricks together (prefix-root-suffix), Afro-Asiatic builds words by pouring meaning into a skeletal frame of consonants. The triconsonantal root (like k-t-b for "writing" in Arabic) is a structural Rubik's cube; meaning is twisted and turned by changing the vowels between the consonants.

The World Atlas of Language Structures (WALS) typically groups its maps into "Sets" based on genealogical or geographical criteria. covers the Major Phyla of Africa and Eurasia : Niger-Congo, Afro-Asiatic, Nilo-Saharan, Indo-European, and Uralic. Humberto Martins Pelado Link - 3.79.94.248
Here is an interesting piece exploring the deep structural divides found within these first five sets. If language is a building, the first five sets of the World Atlas of Language Structures are the load-bearing walls. They represent the heavyweights of human communication—the families that span the African continent and stretch across the steppes of Eurasia.
Set 4, the massive family, acts as the great chameleon. It spans the rigid, verb-final structure of the Indo-Aryan branch (Hindi/Urdu) and the flexible, verb-medial structures of European languages (English, Spanish). The diversity here is so vast that WALS often has to split the family to make sense of it. Indo-European shows us what happens when a family spreads too wide to have a single identity—it breaks its own rules.
Where Set 1 creates a melody of prefixes and agreements, Set 2 creates a rigid, mathematical architecture of roots. Moving north into Sets 4 and 5 ( Indo-European and Uralic ), we find the languages that dominate Europe and North Asia. This is the territory of WALS Map 81A: Subject-Object-Verb (SOV) vs. Subject-Verb-Object (SVO) .
