learning parts of speech

When we study parts of speech in Russian (or former Soviet) schools, we explain them. We often simply say that “(that part of speech) answers to (some kinds of questions)”.
For example:
“наречие отвечает на вопрос …” (“an adverb answers the question …”),
“существительное отвечает на вопрос что? или кто?” (“a noun answers to the question what? or who?”),
“глагол отвечает на вопрос что делать?” (“a verb answers to the question what to do?”),
etc.

There is a little interesting thing about adverbs. There are several questions they answer.
To remember them easily, we use some trick, – the enumeration of those questions is composed with a rhythm like a poem. Here it is: “где, куда, когда, откуда, как, зачем и почему”.

There is another poem-like enumeration of verbs that differ from others
in the way they
are declined. This enumeration is long, like a small poem, and I don’t remember that rule and those verbs now.
