How many letters comprised the Latin alphabet?

The Latin alphabet originally consisted of 21 letters in its earliest forms, which were adapted from the Etruscan alphabet. Over time, it evolved, and additional letters were introduced, including the letter 'Y' and 'Z'. By the time the modern Latin alphabet became widely adopted, it had expanded to include 26 letters.

The choice of 23 implies the inclusion of the letters that eventually evolved into the full alphabet, missing out on the contributions that led to its standardized form. In studying English and many other languages that use the Latin script, the comprehensive and current version contains all 26 letters. Thus, acknowledging the historical adaptations and developments is crucial in understanding the evolution of the alphabet.

In summary, while the answer reflects an understanding of the changes within the Latin alphabet's history, it does not account for the complete set recognized today, which totals 26 letters.
