Questions & Answers about Lo que construyes es robusto para ser tan liviano.
Why do we use para ser here instead of por ser?
In this context, para establishes a comparative standard or expectation. When you say something is robusto para ser tan liviano (sturdy for being so lightweight), you mean it is surprisingly sturdy considering its weight. If you used por ser (because of being), it would change the meaning to cause and effect: 'It is sturdy because it is so lightweight.'
Why does the sentence start with Lo que instead of just Qué?
Lo que translates to 'that which' or 'the thing that'. In Spanish, you cannot use the question word qué to mean 'what' in a declarative statement like 'What you build...'. Whenever 'what' doesn't ask a question but refers to an abstract idea or action, you must use the neuter relative pronoun lo que.
Why is there a 'y' in construyes?
For verbs ending in -uir (like construir, destruir, huir), a y is added before the ending in all present tense forms except the nosotros and vosotros forms. This spelling change happens to preserve the correct pronunciation, as an unaccented 'i' between two vowels naturally turns into a 'y' sound in Spanish.
Why do we use tan instead of tanto before liviano?
