Is each and every correct English?

"Each and every" is grammatically correct English. It's a common idiom used for emphasis, meaning every single one.

For example:

* Each and every student was required to complete the assignment.

* Each and every detail of the plan was carefully considered.

However, it's important to note that while it's grammatically correct, it can sound a bit formal or overly emphatic. In casual conversation, it's often more natural to simply use "every" or "each."
