The Russian word for mouse is мышь. It is a third declension feminine noun that declines like this:

Sample sentences:

¹ Apparently this superstition was held in English speaking countries as well:

A flayne Mouse rosted, or made in powder, & drunk at one tyme, doeth perfectly helpe such as can not holde or keepe their water: especially, if it be used three dayes in this order. This is verie true and often proued.

From Lupton's “Thousand notable things,” quoted in A Dictionary of Superstitions.

Всходы is a fun little word. The prefix вс- means upward. The root ход- means go. When you put them together into a word that is only used in the plural, it means sprouts, i.e. the tiny little beginnings of plants that have just come up out of the soil. Here's a sample sentence:

Under the influence of books like “In Defense of Food: An Eater's Manifesto” by Michael Pollan and “Animal, Vegetable, Miracle: A Year of Food Life” by Barbara Kingsolver, I decided to do some container gardening on my patio. I went to the farmer's market and bought some Green Zebra tomatoes. I liked them so much that I squeezed out some seeds, fermented them and planted them:

Since работать/поработать means “to work,” you will want to be able to use it to say that so-and-so works for so-and-so. Beginning students of Russian often use the word для as the most generic word for “for,” (not the best idea, incidentally), so one might be tempted to translate “I work for Honeywell” as «Я работаю для фирмы “Хоневелл”». Nope, that would be error. When you want to express the idea that you work full time for an organization, the prepositions you want are в and на followed by the prepositional case. (Follow the general guideliness for selecting на.)

Now here is a subtlety. If you work for a company or organization part time, then you work на followed by the accusative case:

¹ Фирма is normally a на word. Why the heck the Russians say в in this context is a mystery to me.

If you want to express the idea that someone works “as something,” then you put the profession in the instrumental case without a preposition:

The corresponding question would be «Кем вы работаете?» “As what do you work?” Although that awful translation captures the grammatical ideas, a good translation would be simply “What do you do for a living?”

The verb работать/поработать can also mean “to work on” in the sense of “to fine tune one's skills,” “to improve something.” Thus “I'm working on my pronunciation” comes out «Работаю над произношением». Other examples:
