Translation:I don't drink
I just want to confirm that the NY here in the middle of the word is just a palatalized N, not a syllable, right? This is a two syllable word, not three syllable, right? Swahili appears to be so phonetic that the lack of recordings mostly is not a problem, but for this, a recording would really help.
The easiest method to remember how a verb is conjugated is the STROVE method:
Subject- Si (I don't) Tense- Present tense will change the end vowel to 'i' in a negative (presently) Relative- (not used here) Object- (not used here) Verb- nywi (drink (present tense)) Ending- (not used here)
Grammatical term for relative pronoun. Technically it can be added to the ending or as a relative infix, but it's more advanced stuff (I've read it for reference, but haven't gotten to using it in my studying/practice yet). It's explained pretty well here: https://www2.ku.edu/~kiswahili/pdfs/lesson_59.pdf (that website is an awesome reference for learning swahili)
They are not on the cell phone app, unfortunately. On the computer interface, they are at the beginning of each unit of lessons (if that's what we call them) under the list of lessons for the unit. If you are using your cell phone, though, you can go in through a browser and see the Tips and Notes, and then you can simply exit and do the lessons through the app.
