Questions & Answers about Es necesario saber la teoría para llegar al nivel avanzado.
Why doesn't es necesario trigger the subjunctive mood here?
Impersonal expressions like es necesario, es importante, or es bueno only trigger the subjunctive if there is a specific subject introduced with the word que. For example, if you were telling a specific person they need to know the theory, you would say es necesario que sepas la teoría. Because this sentence is making a general statement for everyone, we skip que and just use the infinitive verb saber.
Doesn't llegar mean "to arrive"? Why is it translated as "to reach"?
Yes, llegar is most commonly used for arriving at a physical destination like a city or a house. However, it is also the standard verb for reaching a goal, a stage, or a level in Spanish. Just like with physical destinations, it must be followed by the preposition a (which combines with el to make al nivel).
Why is saber used here instead of conocer for knowing the theory?
While conocer is used for being familiar with a person, place, or piece of art, saber is used for facts, information, or deeply understanding a subject like la teoría. If you used conocer, it would sound more like you are just aware that the theory exists, rather than actually understanding how it works.
Why do we use para instead of in this sentence?
