All four are Bantu languages sharing a common ancestor, but they differ in geography, tonality, and mutual intelligibility.
| Language | Primary Countries | Speakers (approx.) | Tonal? | Script |
|---|---|---|---|---|
| Luganda | Uganda | 7 M | Yes | Latin |
| Bemba | Zambia, DRC, Tanzania | 5 M | Yes | Latin |
| Nyanja (Chichewa) | Malawi, Zambia, Mozambique | 15 M | Yes | Latin |
| Tsonga | South Africa, Mozambique, Eswatini, Zimbabwe | 5 M | No | Latin |
Despite shared Bantu roots (similar noun‑class systems, SVO word order), each language has evolved distinct phonology and lexicon.
