contributed to the formation of the protolanguage, in particular southern Nigerian and western Bantu languages. While the phonetic source of the final negation marker (fa/f/wa~va) in the creoles remains unclear, we argue that its syntax and functions, which also include emphasis, show a strong parallel with utterance-final markers in the contributing African languages. Although the trigger of these patterns should be sought in the earliest African contribution from Nigeria, their entrenchment and full grammaticalization can be attributed to heavy secondary contact with languages of the Kongo Bantu cluster.
