How are English words formed? What about the grammar rules?

English was created by the British ... there is a saying that English has roots. On the basis of the root, many words such as interest-interest/interested <; It's an adjective or something, but you should be interested in learning English and don't get bored. It's actually quite simple. Remembering a word and then remembering some ways of word evolution are very useful for understanding words, such as reading comprehension methods, such as adjectives with suffix ly becoming adverbs and so on. However, some irregular levels are troublesome, so it is necessary to remember the past tense and past participle of irregular verbs separately and accumulate them by yourself. However, our teacher gave us a comprehensive summary of the past tense and past participle of irregular verbs, which we thought was quite good. Some things don't need to be memorized deliberately. If you look at them more, you will remember them.
