Correction strategy
Do not try to fix every sentence at once. Choose one repeated mistake, learn two correct examples, and reuse them until they feel automatic.
Fix and repeat
Say three sentences aloud using one Spanish expression from this page. Then replace one word to make the sentence personal.
- Read the Spanish example slowly.
- Repeat it without looking at the English meaning.
- Change the person, time or place.
