Which language not have an alphabet?

It's not accurate to say that a language "doesn't have an alphabet". All languages have a system for representing sounds, but those systems vary greatly. Here's a breakdown:

* Alphabets: These are systems where individual letters represent individual sounds (like English).

* Abjads: These systems only represent consonants, leaving vowels to be inferred (like Arabic).

* Abugidas: These systems use symbols representing consonants, but with diacritical marks to indicate vowels (like Devanagari script used for Hindi).

* Syllabaries: These use symbols to represent whole syllables (like Japanese hiragana and katakana).

* Logographic Writing Systems: These use symbols to represent whole words or morphemes (like Chinese characters).

So, there's no language that "doesn't have an alphabet". They all have their own unique writing systems.

For example, Chinese doesn't have an alphabet. It uses logographic writing, where each character represents a word or morpheme.
