There are dozens of strings that you should avoid using when naming a form control (i.e. input field). Because WordPress uses the same names for its query parameters, a form submission including those names could lead to unexpected behavior.

The unavailable names are listed in the FAQ answer for Are there any reserved or unavailable words for the name of an input field?

The best practice to utilize when attempting to avoid unavailable names is to add a prefix or suffix to the name. For example, use your-name or name-1234 instead of name.
