If you don't have a rich vocabulary in English, you can say "I don't have a wide range of words to choose from" or "I don't have a large vocabulary." You can also say "I struggle with vocabulary" or "I find it hard to express myself because I don't know the right words." It's important to note that having a limited vocabulary is a common challenge for language learners, and there are many ways to improve your vocabulary over time. Some suggestions include reading widely, learning new words through context, and using a dictionary or thesaurus to look up words you don't know. With time and practice, you can expand your vocabulary and become more confident in your ability to communicate in English.
