Every beginning Russian student knows the word вопрос means ‘question.’ It's a perfectly regular hard first declension noun:

Sentences with this word are fairly straight-forward:

The word also has a secondary meaning of ‘issue’:

* мучать is a slightly more conversational version of мучить.

The Russian words студент and студентка are false cognates... sort of. A false cognate is a word in one language that sounds similar to a word in another language but does not share the same meaning. For instance, the English word ‘embarrassed’ is a false cognate with the Spanish word ‘embarazada’, which actually means pregnant. (The latter brings up all sorts of amusing errors when a gringa says “Estoy embarazada” meaning to say “I am embarrassed” but ends up stating “I am pregnant.” Alas, cross-cultural communication is full of such errors, and most of them are much more subtle than that one.)

Anyhoo, the word for “male college student” declines like this:

and the word for “female college student” declines like this:

A college student is not the same as a high school student, so you can't use these words to talk about kids in grade school or high school. Here are some sample sentences.

Russian has a whole series of verbs that mean ‘to enter.’ One means to enter by one's one power, another by vehicle, another by water, another by crawling, another by running... Frankly, I expect that if we ever achieve interstellar space travel, it will develop verbs that mean ‘to enter by space’ and ‘to enter by hyperspace.’ For today we will focus on ‘to enter (by one's own power)’ or ‘to walk in to.’ That verb is:

Note that the place you enter appears in the accusative case after the preposition в.

One of the most flexible verbs in the Russian language is заниматься/заняться. In it's most generic sense, one can translate it as “to be occupied [with something].” Today we will discuss it in the sense of “to study.” It conjugates like this:

In the sense of “to study” the verb is used for advanced studies:

The perfective of the verb can mean “to start studying”:

A majorly important verb in Russian is договариваться/­договориться. It means ‘to come to an agreement about doing something.’ It conjugates like this:

The verb is first of all used to say you agree with the plans that have been discussed. In that context one uses it almost exclusively in the plural:

Almost every conversation about making plans includes the word that way. The verb can also be used in the sense of “to make plans”:
