"We are brother and sister."
Translation:Мы брат и сестра.
А is used as a means of juxtaposition.
И is used to connect two "similar" things together.
А is regularly used in the following types of sentences:
- I am an engineer, and you are a medic. = Я инженер, а ты медик.
- I am an engineer, and you are not. = Я инженер, а ты нет.
- I am eating and you are sleeping. = Я ем, а ты спишь.
- I am eating and you aren't. = Я ем, а ты нет.
- I like apples/I am eating/I am a medic. And you? = Я люблю яблоки / ем/ медик. А ты?
("I" and "you" are just used for clarity here)
Note how you "compare" two things here (like, side to side). But there is NO contradiction. I mean, if I am an engineer, there is nothing to prevent you from being a medic.
There are also more advanced cases of "narrative" contrast, which I am not sure we even introduce in the course:
- На столе кубик, а на кубике лилия. = A cube is on the table, and there a lily on the box.
- Я ем яблоки, а это витамины и всё такое. = I eat apples, and that's vitamins and stuff, you know
Here, you might understand it as "and now one more thing you did not expect me to say".
Most computers allow for Russian Keyboard installs. Go to Control Panel > Language > Add Language
Under R, you should find Russian (русский) . Click on Add Input Method, and Install the Russian or Russian Mnemonic keyboard.
Wait for it to install, and boom. Russian keyboard. Don't pay extra money for one. To change keyboards quickly, just press Windows Key + Space (This is useful if you're on a chatroom or video-game.)
The Russian Mnemonic keyboard translates the syllables you type automatically (Though not 100%, you'd have to adjust accordingly). Though be warned, Russian keyboards have a different layouts than the traditional QWERTY keyboard. If you want to move to a post-soviet state (Or you're in one already), be warned, computers there would generally be in this layout. - (http://www.linguanaut.com/images/russian_keyboard2.gif).
