Classical Chinese grammar is a way of arranging words and phrases to make sentences in old-fashioned Chinese. It's a bit like putting together a puzzle or building blocks, where each piece (a word or phrase) fits together in a certain way to create a complete idea.
Now, unlike modern Chinese where you might use lots of different words to say the same thing, in classical Chinese, the same word or phrase can have lots of different meanings depending on the context. So, it's really important to pay attention to the order of the words and how they fit together to make sense.
Another important thing to know is that classical Chinese has a different way of showing tenses (past, present, future) compared to modern Chinese or English. That means you have to pay close attention to the wording to figure out when something happened or will happen in the sentence.
Overall, classical Chinese grammar is a bit of a puzzle that you have to put together, while also keeping in mind that the same piece (word or phrase) can have lots of different meanings depending on the context and the timing of the event being described.
