"I am buying a bus ticket"
Translation:Ninanunua tiketi ya basi
If you look up a word in DuoLingo's dictionary, it will list the relevant discussions. It took me awhile to discover where the dictionary was hiding so I got in the habit of keeping a file open when doing a lesson and copy/pasting the discussion URL for information I couldn't absorb at the time but knew I would want to return to later. (This is the computer version; I don't know what options you have for the app.)
