Learn Spanish words and grammar with a clear, focused practice routine. Dulcinea is free, works offline, and saves your progress on your device. No account is needed. BUILD VOCABULARY THROUGH RECALL Practice a frequency-guided collection of 10,000 Spanish dictionary entries. Move from matching and multiple choice to recalling translations in both directions. Review words over time and see how many you have mastered. PRACTICE GRAMMAR IN CONTEXT Translate source-backed Spanish and English sentences through choices and written answers. Lessons combine vocabulary and grammar, adjust to your learning history, and revisit missed questions until you get them right. The course includes practice for 199 grammar concepts within a 200-concept outline. KEEP YOUR MOMENTUM Correct answers advance immediately with a brief green check. Answer controls stay above the keyboard, and Return checks your answer. Type your responses or optionally use on-device transcription on supported devices, with editable text before submission. START AT YOUR LEVEL Begin from the basics or take a short level check. You can check your level again in Settings without erasing your learning history. SEE WHAT YOU HAVE LEARNED Track your daily streak, words mastered out of 10,000, and grammar progress. Browse practiced words and concepts, exposure counts, and recall evidence. These are course learning measures, not a fluency or CEFR certification. OPTIONAL SPEAKING AND LISTENING Copy a prompt based on your recent vocabulary and grammar, then paste it into your preferred external chatbot for voice practice. You choose the service and its voice features; its terms and any costs apply. External practice does not change your Dulcinea progress.
