Questions & Answers about Esa corona es más ligera que la que vimos en el museo, pero parece cara.
What does esa mean and how is it different from esta or aquella?
esa is a feminine singular demonstrative adjective meaning that. Unlike esta, meaning this (closer to the speaker), and aquella, meaning that over there (farther from both speaker and listener), esa points to something relatively close to the listener or a bit farther from both. In English it corresponds to that.
How do you form a comparative in Spanish with más ligera que?
Why is it ligera and not ligero?
Adjectives in Spanish must agree in gender and number with the noun they modify. Since corona is feminine singular, the adjective takes the feminine form ligera. If it were a masculine noun, you would use ligero.
There are two instances of que in the sentence. Do they serve the same function?
No. The first que is part of the comparative construction (más… que = than). The second que is a relative pronoun meaning which, introducing the clause que vimos en el museo (which we saw at the museum).
