I am trying to grasp the lesson on articles. Can someone differentiate all of the following. I understand some of them, but I'd like to see all of them together using the same "noun" for comparison. And are some not valid syntax?
le gerku
lo gerku
le ci gerku
ci le gerku
lo ci gerku
ci lo gerku
lei gerku
lei ci gerku (lu'o ci le gerku?)
ci lei gerku
loi gerku
loi ci gerku (lu'o ci lo gerku?)
ci loi gerku
