'It is a very comprehensive and full description that Rennison has produced, and it is a great contribution to linguistic knowledge to have such detailed documentation of a truly endangered language.' - SOAS Bulletin, Vol61, No. 198
'Altogether John Rennison's work represents for his completeness not only a noteworthy contribution to our knowledge about the languages of the region (of Burkina Faso) enriching our data on the Gur family, but it is also an important documentation of a language which, being spoken by only a few people, could easily disappear and be lost to our research in a not so far distant future.' - Anthropos 4/6 1998
