Spanish - Reasons
Lesson 39 of 159
Goal: Give and ask about causes
Free Spanish lessons with guided practice, audio, and speaking support.
Welcome to Lesson 39 — a short, friendly practice on talking about reasons. Listen, notice the patterns, then say them out loud to make them yours.
Level B1: In this lesson you’ll practice common Spanish frames for giving reasons, asking if something caused a result, and connecting causes to actions (e.g., “Por eso…”, “Decidí … por …”, “¿Qué provocó…?”). The activities are CEFR-aligned and focus on real conversational uses so you can explain choices and ask for causes with confidence.
After this lesson you'll be able to:
- Use B1-level frames to give and ask about reasons in everyday situations.
- Recognize and produce connectors that link cause and result (e.g., Por eso, Una razón es que).
- Practice responding aloud so you get comfortable explaining motives and problems.
