Related languages
Soli is closely related to neighboring Bantu languages such as Tonga, Lenje, and Lunda, sharing significant lexical and grammatical features.
Writing system
The language is traditionally oral, but recent literacy efforts have employed the Latin alphabet, adapting it to represent Soli phonology.
Language vitality
Soli is considered a vulnerable language. While it remains the primary means of communication within Soli communities, increasing contact with dominant languages such as English and Bemba has led to language shift among younger generations.
Documentation and research
Linguistic documentation of Soli is limited. A handful of academic articles and descriptive surveys have been produced, focusing on phonology, grammar, and sociolinguistic context. No comprehensive grammar or dictionary is widely published.
ISO 639‑3 code
As of the latest ISO listings, Soli does not have a distinct ISO 639‑3 identifier separate from related dialect clusters; it is often subsumed under broader regional language codes.
