"Gotcha" is a contraction of "got you." It has two meanings. The first is literal: I have you, or I understand you. "Gotcha, I'll be there at 8." The second is trickery: I fooled you. "Gotcha!" you shout after a prank. The tone and context decide. It is a word with a split personality.

Gotcha is informal. It is used in speech and texting. It is not for formal writing. It is friendly. It is quick. It is a way to say, "I heard you" or "I caught you." It is a small word with a big range. It can be a confirmation or a trap.

How it is used

• Understanding: Gotcha, that makes sense.
• Surprise: Gotcha! You didn't see me.
• Prank: Gotcha! Your shoe is untied.
• Agreement: Gotcha, I'll handle it.

Gotcha is not always welcome. A "gotcha question" is a trick question designed to trap a politician. A "gotcha moment" is a public embarrassment. The word can be playful or malicious. It depends on the intent. In a friendly chat, it is fine. In a debate, it is a weapon.
