which language has the most letters in its alphabet?

Thai has 76 letters: 44 consonants, 28 vowel forms and 4 tone markers.

I know Chinese at an low-intermediate level, and I've been a high school English teacher in America. In my opinion, Chinese won't replace English as an international language. The tones are too difficult for the majority of non-native speakers to master to high proficiency, and the characters and writing system are, as you say, much more difficult than an alphabetic system.

Armenian alphabet has 39 letters

Russia has like 32.... China doesn't have an alphabet per se, but there's more than 2000 characters

Tamil Has most letters 247

the japanese language! there are 3 kinds of writing such as kanji, the difficult one that came from chinese readings, 2nd is hiragana translating word one by one, and the last is katakana translate foreign words to japanese alphabet

when you say "us " I presume you are meaning the English Language.

But even in Europe there are variations , for instance the Portuguese don't have a "Y".

Chinese, definitely. But they don't use letters, they use characters which are like pictures that spell out words.

I think it was Hungarian, but I'm not sure. It has like 36 letters.

i think it's japanese...like they have katakana, kanji, and hiragana.....even romaji counts....just take a look at this pic....
