When I lived in Madrid, I speak Spanish very well, but now my Spanish is poor.

It sounds like you might be experiencing some language attrition, which is quite common when you stop using a language regularly. Here are some tips to help you improve your Spanish skills again: 1. **Practice Speaking**: Find a language exchange partner or a tutor to practice speaking regularly. Websites like Tandem or italki can connect you with native speakers. 2. **Watch Movies and Series**: Watch Spanish films or series with subtitles in Spanish to improve your listening skills and pick up new vocabulary. 3. **Read in Spanish**: Try reading books, articles, or news in Spanish. Start with something easy and gradually increase the difficulty. 4. **Use Language Apps**: Apps like Duolingo, Babbel, or Memrise can help you practice vocabulary and grammar in a fun way. 5. **Listen to Music and Podcasts**: Engage with Spanish music, podcasts, or audiobooks to immerse yourself in the language. 6. **Join Spanish Groups**: Look for local or online groups where you can interact with other Spanish speakers, such as meetup groups or social media communities. 7. **Set Goals**: Set specific, achievable goals for your language learning, such as learning a certain number of new words each week. By regularly engaging with the language, you should see improvement over time. ¡Buena suerte! (Good luck!)
