Why is "he does does" considered grammatically incorrect?
The repetition of the auxiliary verb "does" is redundant and doesn't follow standard English grammar rules. It's typically a mistake or a typo. Instead, use a single "does" or rephrase for emphasis.

You can use phrases like "he really does", "he certainly does", or "he actually does" to add emphasis without grammatical errors.
In what contexts might I mistakenly use "he does does"?
This error might occur in informal speech or rapid writing due to a slip of the tongue or a typographical error. Proofreading can help catch and correct such mistakes.

Repeating "do" can occur in questions like "He did, did he?", which is used for emphasis or to express surprise, but the structure and intent are different from a simple statement like "he does does".
