Questions & Answers about Para ser sincero, tenemos que aclarar lo que piensas.
Why does this sentence use lo que instead of just qué for "what"?
In Spanish, qué (with an accent) is used for direct questions, like ¿Qué piensas? (What are you thinking?). In this sentence, "what" isn't a question; it means "the thing that" or "that which". Because it refers to an abstract idea rather than a specific masculine or feminine noun, we use the neuter relative pronoun lo que.
Why do we use para instead of por in para ser sincero?
Would the word sincero change if a woman says this sentence?
Yes, it would. Even though it acts as an introductory phrase here, sincero is still an adjective describing the speaker. A female speaker would say Para ser sincera.
Could I use lo cual instead of lo que to mean "what" in this sentence?
