Remember the Spanish you learn. New words and grammar come back in a daily review until they stick. Set a daily word goal and follow a guided grammar path. New words and grammar topics feed one daily review, and your answers shape what comes back: difficult material returns sooner, while material you know well gets more time between reviews. DAILY REVIEW FOR VOCABULARY AND GRAMMAR New vocabulary and completed grammar topics get their own review schedules in the same daily routine, so practice continues beyond your first encounter. Review vocabulary in both directions, from understanding Spanish to recalling it yourself. WORDS IN CONTEXT Explore 6,300+ built-in words with 18,900+ bilingual examples. See how words work in different sentences and browse themed lists. Search in Spanish or English when you want to look something up. HEAR HOW IT SOUNDS Play pronunciation audio for 11,000+ built-in words, verb forms, and grammar answers, so you learn how Spanish sounds as well as how it's spelled. GRAMMAR PRACTICE WITH EXPLANATIONS Work through 70 guided drills across 15 units, from ser and estar to past tenses, commands, the subjunctive, and si-clauses. Practice conjugating verbs and choosing grammar that fits the sentence. Answer explanations help you understand why a form fits and learn from mistakes. Open a concise Quick guide when you need a refresher. PRACTICE WHAT NEEDS ATTENTION Choose vocabulary, grammar, or conjugation for extra practice. Track your learning and review activity, and see which material is going strong. With CocoDrilo Pro, repeated misses in Daily Review can become a personalized Focus session. Use your recent review history to work on words and grammar that need more attention. BRING YOUR OWN VOCABULARY With CocoDrilo Pro, create personal lists, add words, or import vocabulary from pasted text or CSV, TSV, and plain-text files. Bring material from a class, tutor, or your own reading into the same learning and review routine. Preview your import and check for existing words before adding it. COCODRILO PRO Pro adds personal vocabulary and import, detailed insights into what needs attention, personalized Focus practice, higher daily goals, optional extra review, and more control over practice sessions and grammar settings. Whether you're starting Spanish or returning to it, give what you learn a place in your daily routine.
