Is very same thing goes grammatically correct?

"Very same thing" is grammatically correct, but it's often considered redundant and awkward.

Here's why:

* Redundancy: "Very" and "same" both convey a sense of complete identity. Using both words together is unnecessary.

* Awkwardness: The phrase sounds stilted and unnatural in most contexts.

Here are some better alternatives:

* The same thing: This is the most natural and concise way to express the idea.

* Exactly the same: This emphasizes the complete identity of two things.

* The very thing: This emphasizes the importance or relevance of something.

Example:

* Original: "I want the very same thing you ordered."

* Better: "I want the same thing you ordered."

* Even better: "I'll have the same as you."

Remember, conciseness and clarity are key to good writing!
