Letters, the symbols of writing, the earliest letters, are an early hieroglyphic combination used by the Semitic people in the East (known as the northern branch of Semite in modern classification), which appeared between 1700 BC and 1500 BC.
Icons and ideographic symbols developed by primitive people are the prototypes of modern letters, such as cuneiform and hieroglyphics. BC 1000, there are four other kinds of letters, which are developed from the Semitic letters in the east, and the letters used by the southern branch of the Semitic people in the west (called the southern branch of Semite in modern classification), Canaanite letters, Arabic letters and Greek letters.
Around 500 BC, the Roman alphabet evolved from the Greek alphabet. By 20 15, all languages in western Europe (including Irish, Dutch, French, German and other languages) will use this alphabet.
Explain in detail:
1, a phonological term. The representative word of initials, abbreviated as "mother". Wang Songying-lin's Yuhai Wen Yi Primary School: "Guang (Sima Guang) has a note on cutting words, with 384 sounds in 36 words." In the Qing Dynasty, Qian Daxin wrote "A New Record of Letters of Fasting by Ten Drivers": "Thirty-six letters were unknown before the Tang Dynasty. According to legend, Wen was also a shaman in the late Tang Dynasty because monks kept out the cold.
2. The minimum writing unit of pinyin characters or phonetic symbols. Such as: English letters; Chinese Pinyin. The word letter comes from the Sanskrit Modo (Sanskrit mata).
Sanskrit Modo originally refers to vowels, but later the meaning of Sanskrit has expanded, and the consonants are also called Modo. After the word was introduced into China, phonologists only used it to represent initials. Before that, there was no special name for initials in China. People use two syllables to represent initials, and the two syllables of the upper word and the incised word indicate that the two words have the same initials.
At the end of the Tang Dynasty, inspired by the Sanskrit alphabet, monks assigned a representative word to each sound category, which is the alphabet. The remnants of letters unearthed in Dunhuang are listed as "not fragrant and not bright ..." with 30 letters. Later, some people "benefited from the humble service of the mother bed country", with a total of 36 letters.
