Greek alphabet is a letter used in Greek, and it is also widely used in mathematics, physics, biology, chemistry, astronomy and other disciplines. Greek alphabet, similar to Latin alphabet and Cyrillic alphabet, is a complete phonemic text. Greek alphabet is the earliest writing system in the world in which letters represent vowels and phonemes. Cyrillic letters and Georgian letters used in Russian and Ukrainian are all developed from Greek letters, so people who have studied Russian will feel deja vu when they use Greek letters.
The Greek alphabet originated from the Phoenician alphabet, which has only consonants and is written from right to left. The vowels in Greek were developed, and the Greeks added vowels. Because the Greeks

Our writing tool is a wax board. Sometimes the first line is written from right to left, and then from left to right, which becomes the so-called "cultivated land" writing method, and then gradually evolves into all the writing methods from left to right. The direction of the letters is also reversed. The Romans introduced the Greek alphabet, changed it into Latin alphabet with a little change, and it became popular all over the world. Greek letters are widely used in academic fields, such as mathematics. Cyrillic letters also evolved from Greek letters. The English word alphabet (letter) comes from the alphabetum in vulgar Latin, and the alphabetum comes from the Greek word α λ φ α β ο ν (transliteration of Beton), which is the synthesis of the first two Greek letters α(Alpha) and β(Beta).
Expansion symbols are often added above or below the ancient Greek letters, such as acute notes, stress, stress, tilde, partials, rough symbols, softening symbols, etc., so there are 26 different ways to write the vowel letter α in ancient Greek.
Sharp sound: the pronunciation of this letter should be hard and flat.
Stress: the pronunciation of this letter is strong and the tone is falling.
Up and down symbols: this letter is pronounced strongly and pronounced in a rising tone.
Gruff symbol: [h] in ancient Greek for vowels. The consonant ρ always comes with a thick word at the beginning of a word.
Soft gas symbol: indicates that there is no [h]. Although two ρ always appear in the middle of words, they were originally written as the first ρ with a soft symbol and the second with a gruff symbol; Greek ellipsis.
Subscript: placed under the letters α, η and ω, indicating the long vowels α, η and ω. Sometimes written as normal-sized lowercase letters adjacent to uppercase letters.
Diaphragm: placed on the letters ι and λ, indicating that this vowel is pronounced separately from the vowel before it.
The diacritical marks are written above lowercase letters and above the left of uppercase letters. In the case of diphthongs or diphthongs, the second vowel accepts phonetic symbols. Breathing symbols are written to the left of acute notes or accents, but below the accented notes. Stress symbols are written above partials, and sharp sounds or stress symbols can also be written between two points.
In modern Greek, all stress symbols are unified into a substitute symbol, that is, acute notes. The use of breathing symbols is abandoned, but partials remain. Of course, if you use Greek letters as specific codes, you don't need to add additional symbols.
