"The Greek alphabet (Greek: ΕλληνικÏŒ αλφάβητο) is a set of twenty-four letters that has been used to write the Greek language since the late 9th or early 8th century BC. It was the first alphabet in the narrow sense, that is a writing system that uses a separate symbol for each vowel and consonant. It is the oldest alphabetic script in continuous use today. " "Some letters can occur in variant shapes, mostly inherited from medieval minuscule handwriting. " "Obsolete letters The following letters are not part of the standard Greek alphabet, but were in use in pre-classical times in certain dialects. The letters digamma, san, qoppa, and sampi were also used in Greek numerals. Digamma ϝαῦ δίγαμμα San ϻάν σάν Qoppa ϙόππα κÏŒππα Sampi δίσιγμα σαμπá¿– " "In the polytonic orthography traditionally used for ancient Greek, vowels can carry diacritics, namely accents and breathings. The accents are the acute accent (´), the grave accent (`), and the circumflex accent (á¿€). In Ancient Greek, these accents marked different forms of the pitch accent on a vowel. By the end of the Roman period, pitch accent had evolved into a stress accent, and in later Greek all of these accents marked the stressed vowel. The breathings are the rough breathing (῾), marking an /h/ sound at the beginning of a word, and the smooth breathing (á¾½), marking the absence of an /h/ sound at the beginning of a word. The letter rho (ρ), although not a vowel, always carries a rough breathing when it begins a word. Another diacritic used in Greek is the diaeresis, indicating a hiatus. In 1982, the old spelling system, known as polytonic, was simplified to become the monotonic system, which is now official in Greece. The accents have been reduced to one, the tonos, and the breathings were abolished."
