With yo (I), estar becomes estoy. Feliz means “happy”: Yo estoy feliz describes how I feel.

Bootstrap Spanish Grammar gives you a structured path through 209 self-contained topics. Each one combines a plain-English explanation, annotated examples, native-speaker audio and exercises. New vocabulary appears in context, and “Why?” feedback helps you understand a mistake instead of guessing the answer again.

Can I start as a beginner?

Yes. The course starts with estar and ser (to be), personal pronouns and simple sentences. It then introduces negation, questions, articles, gender and plurals before moving on to more complex patterns. English explanations, translations and native-speaker audio support you throughout.

Which Spanish grammar topics does the app cover?

The course covers ser and estar, articles and gender, adjective agreement, verb conjugation, object and reflexive pronouns, negation, preterite and imperfect tenses, perfect and future tenses, conditionals, the subjunctive, reported speech and idioms. Browse the 209-topic syllabus above for the complete sequence.

Can I use it with a class or another app?

Yes. Follow the course in order or revisit a grammar point from your class or another app. Save useful examples in your Study List and use the exercises and audio for focused practice between lessons.

How does spaced repetition work?

Phrases you practise return for review at increasing intervals, helping you revisit earlier grammar as you learn new patterns. Use the review feature for ongoing practice. Spaced repetition and “Why?” explanations are available on both iOS and Android.

Is the Spanish grammar app available on iPhone and Android?

Yes. Bootstrap Spanish Grammar is available for iPhone and iPad on the App Store, and Android on Google Play. Check the relevant listing for current device requirements.
