Guosa
The different parts of speech came from particular languages. Most nouns come from Hausa, while verbs and abstracts come from Igbo or Yoruba. Also, words from all three source languages are often joined together to create a word that looks like all three. For example, the Guosa word méni "what" comes from Hausa menini, Igbo gini, and Yoruba kini, all meaning "what".
