There is a common misconception that grammar does not exist in the Chinese language, but this is not true. Chinese grammar rules do exist, they are just very different to those in Indo-European or other language systems. Unlike these languages, Chinese is a very analytic language which is both good news and bad news for language learners.  For instance, in Chinese, there are no complicated rules about conjugations, agreement, gender, plural nouns or tense.

Hanyu Pinyin is the most common form of such Romanization and is used in many textbooks and teaching materials.  Pinyin allows students of Mandarin to focus on their pronunciation, while also enabling them to read and write, without needing to learn complex Chinese characters. Although Pinyin uses the Roman alphabet, the pronunciation of its letters is often not intuitive to English speakers, which is why it must be studied carefully before it can be used. For example, the letter "c" in Pinyin is pronounced like the "ts" in the word "bits", the letter "e" is pronounced like the "er" in the word "hers" and the letter "q" is pronounced like the "ch" in the word "cheap". Due to these differences, it is essential that you learn the correct...
