Questions & Answers about Esta cera silvestre debe de ser de excelente calidad.
Why do we use debe de ser instead of just debe ser?
The phrase deber de plus an infinitive expresses a strong probability, supposition, or deduction. In English, we also say 'must be' for this when we mean 'I assume it is'. If we dropped the de and said debe ser, it would sound like an obligation, meaning 'It has a duty to be of excellent quality.' While native speakers sometimes mix these up in casual speech, strictly speaking, debe de is for guessing or deducing, and deber without de is for rules and obligations.
Why is the word for 'wild' silvestre here instead of salvaje?
Silvestre is used to describe plants, flowers, and naturally occurring products like honey or wax that exist in nature without human cultivation. Salvaje, on the other hand, is generally used to describe wild, untamed animals like a wolf or a tiger, or ferocious behavior.
Could I use cualidad instead of calidad for the word 'quality'?
No, because they mean different things in Spanish. Calidad refers to how good or bad a product, material, or service is, measuring its level of excellence. Cualidad refers to a personal trait, characteristic, or virtue, such as honesty or patience. Since we are evaluating a physical product here, calidad is the correct choice.
Why does this sentence use ser in debe de ser rather than estar to describe how good the wax is?
Being de excelente calidad is treated as an inherent characteristic or defining trait of this specific wax. When categorizing what type of material something is or stating its fundamental attributes, we always use ser. You are stating a fact about its nature, not describing a temporary condition.
