Questions & Answers about Es la estalactita más larga que resplandezca en la oscuridad.
Why is resplandezca in the subjunctive here instead of the indicative?
In this superlative structure (la... más larga que...), using the subjunctive (resplandezca) highlights that we are singling this stalactite out from a hypothetical or infinite pool of things that might fit the description. Using the indicative (resplandece) would imply we are simply selecting it from a specific, already-established group of glowing stalactites.
Where does the z in resplandezca come from?
It comes from the infinitive resplandecer (to shine or gleam). Just like conocer becomes conozca, Spanish verbs ending in -cer preceded by a vowel change to -zca in the present subjunctive.
I thought superlatives used de, like in el mejor del mundo. Why is it que here?
You use de when comparing the noun to a group or a place (like la más larga de la cueva — the longest in the cave). However, when you follow the superlative with a relative clause containing a new verb (like "that shines..."), you must use que.
Is resplandecer the standard word for "to shine"? Can I use brillar?
