Here is the Level 3 flashcard sentence and answer: How did (you(i)) learn to speak French? With books? ¿Cómo aprendiste a hablar francés? ¿Con libros? My question is when to use "a" as in "a hablar". I know to use "a" when there is motion, like with "ir", but otherwise I thought that the infinitive form already implied it. Thank you.
Hi 2101! In Spanish, some verbs need a specific preposition (not always "a") when they are followed by an infinitive. Lesson 6, Level 4 of the Spanish Upgraded program deals with some of the most common verbs requiring a preposition. Hope this helps!
