"Kwa nini huli"
Translation:Why are you not eating
kwa nini ulikula? is 'why did you eat?'
There are different prefixes for negated verbs in the past participle form. I'll use the verb kusoma (to read) in singular and plural:
1st person: Nasom
i. (I am reading - I am not reading)
i(We are reading - we are not reading)
2nd person: Unasoma -
husomi. Mnasoma -
3rd person: Anasoma -
hasomi. Wanasoma -
Those are always the prefixes for negated verbs. For different tenses, the tense infix comes after the prefix indicating negation e.g. si
kusoma (I did not read) and si
tasoma (I will not read). Here is the same verb in the imperative form:
All the comments are good and useful. But this seems a rather subtle point of grammar to be introducing at this point of the course. I find these to be distracting and even a bit annoying when I am trying to pick up the essential points of the lesson. I spent six months getting through this entire course and found way too many of these kinds of somewhat arcane (for a primary, beta level course) grammatical points. Put them in the second course, when and if it ever comes to pass. I doubt it. This course has many flaws and Duolingo seems to be making no progress whatsoever in updating and improving it. I started in August '19 and finished in February '20. Took a pandemic break only to come back to the same kinds of complaints about answers not being updated or corrected. And the same kinds of too sophisticated grammar points for a beginning course. I am also using Pimsleur Conversational, which is quite good and more immediately useful. As well as many other free resources on the web. My wife and I have a Maasai daughter and granddaughter and Kiswahili is really crucial for me as we go to Kenya often. And, of course, there is Maa, but that is different story! Really different. Just letting off steam about this course. I have studied Spanish my entire life, but taking on Swahili is a challenge. Duolingo is somewhat of a disappointment.
