Which society introduced an alphabet the would later become basis for Greek?

The society that introduced an alphabet that would later become the basis for Greek was the Phoenicians.

Here's why:

* Phoenician Alphabet: The Phoenician alphabet was a consonantal script, meaning it only represented consonants. It was developed around the 11th century BC.

* Greek Adoption: The Greeks adopted the Phoenician alphabet around the 8th century BC. They modified it by adding vowels and changing the order of some letters.

* Evolution of the Greek Alphabet: The Greek alphabet eventually evolved into the various forms of Greek script we know today, including the Ionic alphabet, which became the basis for the modern Western alphabet.

Therefore, the Phoenicians played a pivotal role in the development of the Greek alphabet and ultimately influenced the alphabets used by many languages throughout history.
