The Russian word for ‘what’ is что. Although it is written with the letter ч, the nominative/accusative form of the word is most commonly pronounced [што]; in the other cases we do pronounce ч as ч. It occurs in all six cases:

Notice that the only difference between the prepositional and instrumental forms is the двоеточие “double dots” over the prepositional form.¹ Remember that the Russians usually do not usually write the double dots, so context will have to tell you how to pronounce those forms. Some sample sentences:

Somewhere in school every American is taught the rule “never end a sentence with a preposition.” For English it's an assinine rule that has no reasonable justification in the living language.² However, for Russian the rule is real and alive. It's not an artificial rule, as in English, but rather a subconscious part of the living language: no Russian will ever end a sentence with a preposition, not even accidentally. So whenever you are translating a question from English to Russian, and the question ends with a preposition, you need to move that preposition to before its object and then translate. Thus:

Other examples:

Notice in the last example we can leave the preposition out of the response in English, but in Russian you must retain the preposition to justify the case of памятник.

¹ The double dots symbol is often called a diaeresis or an umlaut. The former is theoretically used to indicate that a vowel is pronounced as a complete vowel (not a diphthong) when preceded by another vowel with which it might blend. The latter is theoretically used to indicate that vowel is fronted. Since neither of those instances prevails in the е/ё distinction, “double dots” is a sensible name for the symbol.

² Of course, one can't mention this rule of English without mentioning Winston Churchill's famous definition: “A preposition is a word you can't end a sentence with.” I actually doubt that Churchill said it, but it's too fun not to mention.

Heaven knows why, but the other day I took an online Russian test and was dismayed to discover that I didn't know the Russian word for hairpin. You may wonder why I was dismayed. After all, why does a foreign man need to know that word when he is never going to wear one in his hair? But the way I figure it, some day I might be thrown into a Russian prison and have to macgyver my way out of there. Who knows what tools I might have to use in the process? So “hairpin” is a perfectly sensible word for me to know. By the way, it turns out to be шпилька, and the genitive plural is шпилек. Sample sentences:

Types of шпильки

Шпилька actually has a dozen other meanings as well. For instance, it is sometimes used to mean cotter pins, which is not too surprising considering their shape, as well as other cylindrical items that hold metalwork together. It also means stiletto in the sense of a tall thin heel on a high-heeled show. From that it's not surprising that a girl-band took on the name Шпильки “The Stilettoes.” And it can also be used to mean a jibe/dig/snide comment:

Бежать is the determinate (unidirectional) form of the verb бегать “to run.” It is one of the four most irregular verb stems in the Russian language:

Бежать is more specialized than бегать in that it usually talks about motion in progress at a particular time:

Although the verb does mean “to run,” it's actually used in conversation more often to mean “to take a quick trip” or “to be moving quickly” instead of literally running. The same is true for the English verb “to run” as well, of course.

The verb is also used in the sense of “to precede prematurely”:

And of course the verb is also used in the sense of “to flee”. Although in English the thing you flee from can be a direct object (“We fled Cuba in 1965”) or the object of the preposition ‘from’ (“We fled from Cuba in 1965”), in Russian the thing you flee from cannot be a direct object; it must be the object of the prepositions из/с/от followed by the genitive case:

The Russian word for mushroom is гриб, a perfectly regular end-stressed noun:

There is a huge cultural difference between Russians and Americans in regards to mushrooms. An American looks at a mushroom in the forest and thinks, “Careful! It might be poisonous!” A Russian looks at a mushroom in the forest and thinks, “My little forest friend! I shall pickle you in oil and spices and consume you with friends in the company of vodka and bliny!”

I never used to eat mushrooms. After all, why would a sane human being deliberately put a fungus that grows in the dirt into his mouth? But then I was served home-preserved mushrooms in Russia. Heaven! The Russians know how to spice, bake, can, wrap, and fry mushrooms better than anyone else on the planet. Now it's a rare day that I don't eat mushrooms, or at least do a little interpretive dance in honor of mushrooms after my morning shower.

In English everbody knows the phrase “mushroom cloud.” The Russian equivalent is «ядерный гриб» “nuclear mushroom.” That's not particularly surprising. What would surprise an English speaker is that the phrase is used in Russian phrases that mean “really ugly”:

Бегать is the most generic word in Russian that means “to run.”

Running… nowadays in the lazy West we often run in order to lose weight. That actually makes sense:

It's not usual for a person to regularly run from one place to another, but in such atypical circumstances it is possible to conceive of someone doing such a thing:

The verb is also used to describe the motion of someone running around a place with no set goal or direction, e.g. walking around a neighborhood for pleasure:

Last but not least, the verb is used to indicate a single round-trip in the past. It's not typical in this usage, but still grammatically possible:
