Questions
From Sereer wiki
Polar Questions
Polar questions can seemingly be formed with a sentence-final boundary H added to normal (gradually falling) intonation. Syntactic means of forming questions are unclear at this point.
WH Questions
Work has yet to be done here. WH-questions are (unsurprisingly) formed with the use of WH-words, which appear to be completely unrelated to the subordinating pronouns (e.g. te).
