Learn Russian: Ты меня видишь?

меня is the accusative case form of я (I). Just like in English where "I" changes to "me" when you are on the receiving end of an action, Russian changes я to меня. Since "I" am the person being seen (the direct object), we must use this accusative form.

Why is the word order "You me see" (Ты меня видишь) instead of "You see me" (Ты видишь меня)?

Russian word order is much more flexible than English! Both Ты меня видишь? and Ты видишь меня? are completely correct. Putting the object pronoun (меня) right before the verb is very natural and common in spoken Russian. Because the word меня clearly shows who is being seen, the meaning is clear no matter the order.

Where is the word for "Do" in this question?

Russian doesn't use helper words like "do" or "does" to ask questions. To turn the statement "You see me" into the question "Do you see me?", you simply use the exact same words, add a question mark, and raise your voice at the end when speaking.

Why does the verb end in -ишь?

The dictionary form of this verb is видеть (to see). Because the subject doing the seeing is ты (you, informal), the verb has to change its ending to match. For this specific verb, that means taking off the ending and adding -ишь, giving us видишь.
