Here's why:
* Different alphabets: Languages use different alphabets (or writing systems), so even if a sound is the same, the spelling might vary.
* Pronunciation variations: Even within the same language, pronunciation can change depending on the dialect or region.
* No universal language: There's no single language that everyone speaks.
However, some words come close!
* Numbers: Numbers like "one", "two", "three" often have similar pronunciations and spellings across many languages.
* Interjections: Words like "oh" or "ah" are often shared across languages.
