Here's why:
* Alphabets vs. Writing Systems: Some languages use alphabets, which are sets of letters that represent sounds. Others use syllabic scripts, where symbols represent syllables, or logographic scripts, where symbols represent entire words.
* Distinct Letters vs. Diacritics: Even within alphabets, the number of "letters" can be debated. Do you count diacritics like accents and umlauts as separate letters? Some languages use a lot of diacritics, which could artificially inflate the number.
* Historical vs. Modern Use: Some languages have large alphabets, but they might not be used actively today.
Some contenders for "most letters":
* Khmer (Cambodia): Has a very large alphabet with 74 letters, but it's mostly used for writing the Khmer language.
* Tamil (India): Has a large alphabet of 12 letters, but includes a lot of vowel and consonant combinations, resulting in a significant number of distinct symbols.
* Sanskrit: Has a large alphabet of 48 letters, but it's largely a liturgical language now, not commonly used for everyday writing.
The real answer: It's not about the "greatest number of alphabets" but about the richness and complexity of different writing systems and the ways they represent language. Each language has its own unique way of encoding sounds and meaning.
