Language of the Day, a memento of past geekery

Guosa is an interlanguage, an artificially constructed language designed to serve as a vehicle of intercommunication between people with different native languages. The most popular and famous (or infamous) interlanguage is Esperanto, which was cobbled together from various European tongues. Guosa is, if anything, even less linguistically sophisticated and draws instead from the major languages of Nigeria. The basic principle is that words for concrete objects come from Hausa, whereas abstractions are from Yoruba, Igbo, or one of the many smaller languages spoken in the south. (I think that abstractions include all verbs, but the text isn't as explicit on this point as it could be.)

To give you an idea of the creator's naivete in such matters, his method for choosing between Yoruba and Igbo alternatives is which comes first in alphabetical order! What a perfect recipe for unbalancing the distribution of sounds in your vocabulary, thus creating confusion between many similar-sounding words. (By contrast, Lojban, another constructed language, uses an algorithm that weights various phonemes according to their appearance in five of the world's major languages, including Chinese and Arabic.)

Yesterday, I came across the book Teach yourself Guosa language, which is suitable for anything but. It's just a slim phrase book whose longest text is:

Kudi ti moni, kinshe nke ijakpa. Ẹso fun oyen ijakpa kọ-gbe ijakpa tẹfi.

(Translation: The money that I have is not for the purchase of tortoise. Tell the tortoise dealer to go away with his tortoise.)

Yeah, you'll use that a lot. There's not a word on grammar in the book. I suppose, like Zamenhof, Igbinewka assumes that you can just import your knowledge of the source languages. What about the numerous cases where these languages differ? The book is 22 years old, so I did a websearch to see if the project is still alive. Not only is it, but the Guosa African Cultural Center is located on American soil, in Richmond, VA! Bring us your idealistic nutbars, yearning to teach for free.
