"I don't speak English" or "I am not fluent in English" is a more accurate and natural way to express your limited proficiency in the language. When encountering situations where you struggle to communicate in English, these phrases convey your discomfort or lack of confidence without implying complete ignorance.
The phrase "I don't know English" might lead native speakers to misunderstand your background, as "don't know" suggests a lack of familiarity with the language rather than a mere difficulty in speaking it. Furthermore, using "I don't speak English" prevents others from assuming that you have no ability to learn or understand English at all, which could affect your interactions with them.
To improve your English, it's essential to practice regularly and learn from mistakes. By using more precise and idiomatic expressions, you can better communicate your needs and avoid misunderstandings. Remember, language learning is a journey that requires consistent effort and application.
