Learn German: Nein, es ist falsch.

This sentence is an answer to a yes/no question, not a question itself! While yes/no questions start with the verb, normal statements put the verb in the second position. Here, the verb ist comes right after the subject es. The word Nein and the comma sit outside the main sentence structure, so they do not take up the first position.

Is falsch related to the English word false?

Yes, they are closely related! In German, falsch is used to mean both false and wrong. You can use it to talk about an incorrect answer on a test, taking the wrong train, or something that is fake.

How do you pronounce the sch at the end of falsch?

The German sch makes the exact same sound as the English sh in shoe or fish. Combined with the short ah sound of the a and the l, the whole word sounds a lot like fahl-sh.

Could es refer to a specific object being wrong, like a table or a lamp?

It depends on the object's grammatical gender. The pronoun es (it) replaces neuter nouns, which are words that use das (like das Buch for the book). If you were talking about a masculine word like der Tisch (the table), you would have to say er ist falsch. In this specific sentence, es is likely just a general it, representing a whole situation or statement being wrong.
