Your sentence
Ich habe gegessen ein Apfel gestern.
✅ Corrected sentence
Ich habe gestern einen Apfel gegessen.
WORD ORDER The verb cluster must stay together at the end — gegessen cannot split from habe
CASE ein Apfel is the direct object → accusative → einen Apfel
ADVERB Time adverbs like gestern sit before the object, not at the end
Writing Practice — Spanish · Intermediate
✍️ Prompt: Describe your typical weekend in at least 5 sentences.
Los fines de semana, me despierto tarde y desayuno con mi familia. Después, voy al mercado para comprar fruta fresca. Por la tarde, me gusta leer o salir con mis amigos. A veces hacemos una barbacoa en el jardín.
Excellent use of reflexive verbsme despierto, me gusta are both correct and natural
💡voy al mercado is correct, but suelo ir (I usually go) would sound more fluent here
hacemos needs a subject pronoun for clarity — consider nosotros hacemos or restructure the sentence

For serious learners

Your textbook needs a partner and a tutor.
That's Luga.

Language textbooks are full of activities that assume you have someone else in the room — a conversation partner, a teacher to mark your writing, a classmate to quiz you. When you're studying alone, those exercises just get skipped. Luga fills every one of those gaps.

🎭
"Talk to your partner about…"
Luga plays the other person. Practice the conversation exercise from your book exactly as intended, without needing anyone else.
✏️
"Write a paragraph / email / story and hand it in."
Write it in Luga instead — a paragraph, a formal email, a description of what you did last weekend, a short story in the past tense. Get corrections, grammar explanations, and a score, instantly.
🧠
"Learn the vocabulary for next lesson."
Save the words from the chapter and quiz yourself on them. Luga tests you until they actually stick.
