"Are the plates here?"
That makes a lot of sense, because, if you look at a declension table of noun endings for masculine/feminine/neuter, singular/plural and all 6 cases, there are so many haphazard repetitions of the same letter that, without something besides the ending, Russian would be impossible to understand.
For example, -а is an ending for Masculine singular Accusative (animate) and Genitive cases, for Feminine singular nominative, and for Neuter plural Nominative and Accusative (inanimate). Я has some similar multi-function uses, as well as other endings.
I don't think it's possible to depend solely on the word endings to determine word function. There has to be something(s) else - and word-order is one of those things.
The words are correct, but emphasis changes depending on location in sentence. Presumably, that's what happened here as well.
