* No single definition of "correct" English: There are many dialects and accents of English. What's considered "correct" can vary based on region, formality, and even personal preference.
* Levels of proficiency: People speak English at different levels of fluency. Some may be native speakers, while others are fluent, proficient, or have basic conversational abilities.
* The "English-speaking" world is vast: It includes countries where English is the official language, as well as places where it is widely used for communication.
Instead of focusing on "correctness," it's more useful to consider these facts:
* English is the most widely spoken language in the world: It's estimated that over 1.5 billion people speak English as a first or second language.
* English is a global language: It's used extensively in business, education, science, technology, and international relations.
* English is constantly evolving: New words, phrases, and dialects are emerging all the time, making a rigid definition of "correct" increasingly difficult.
Rather than trying to quantify "correct" English, it's more important to recognize the diverse ways people use and learn English.
