Final answer:
The Ionian Greeks developed a system of vowels, accents, notes, and verse divisions based on the Phoenician alphabet, which served as the basis for the alphabets used in Europe, including English.
Step-by-step explanation:
The Ionian Greeks developed a system of vowels, accents, notes, and verse divisions. Working from the Phoenician alphabet, the Ionian Greeks created their own syllabic alphabet. This writing system proved to be flexible, nuanced, and relatively easy to learn, allowing the Greeks to record literature, poetry, and drama. The Greek alphabet served as the basis for the Roman alphabet and influenced other alphabets used in Europe, including English.
