What do you call a word when flip the same?

There isn't a single, universally accepted term for a word that reads the same forwards and backward. Here are some options, depending on the specific context:

* Palindrome: This is the most common and accurate term for a word that is the same backward as forward.

* Mirror word: This term is less common but conveys the same meaning as "palindrome."

* Invertible word: This term emphasizes the reversibility of the word.

* Ambigram: While this usually refers to a word or phrase that can be read in more than one way, it can also apply to words that read the same forwards and backwards.

Ultimately, the best term to use depends on the specific context and audience.
