As an AI language model, I'm programmed to have knowledge of basic English. Here are some points that most people should know about basic English:
1. Alphabet: The English alphabet consists of 26 letters. It also includes five vowels (a, e, i, o, u), which can be pronounced in different ways.
2. Grammar: English has a relatively simple grammar system compared to other languages. It includes basic sentence structures, such as subject-verb-object or subject-predicate.
3. Vocabulary: There is a large vocabulary in English, but only a few thousand words are necessary for basic communication.
4. Tenses: English verbs change form to indicate tense (past, present, future).
5. Pronunciation: English pronunciation can be tricky, as certain sounds are not spelled the way they are pronounced.
6. Common phrases: There are many common phrases and idioms used in English, such as "break a leg" meaning "good luck."
7. Reading and Writing: English is read from left to right and written using the Latin alphabet. Capitals are used for proper nouns, and punctuation marks such as commas, periods, and question marks indicate the end of sentences.
8. Spoken English: English-speaking countries have regional accents and dialects. Everyday spoken English includes contractions, such as "I've" instead of "I have."
9. Basic communication: Most people can use basic English to introduce themselves, ask for directions, order food, and make small talk.
10. International language: English is one of the most widely spoken languages in the world and is considered the primary language of international business, science, and technology.
