Questions & Answers about Ya he visto la caída altísima de este parque.
How is the word altísima formed here?
It comes from the adjective alto (high/tall). To make an absolute superlative (meaning "extremely" or "incredibly" high), you drop the final vowel and add the suffix -ísimo. Since it describes the feminine singular noun la caída (the drop), it must agree in gender and number, becoming altísima.
Could I just say muy alta instead of altísima?
Yes, muy alta means "very high." However, adding -ísima turns it into an absolute superlative, which makes it even stronger. It translates closer to "extremely high," "incredibly high," or "super high," adding a lot of emphasis to your sentence.
Why is the verb form he visto and not he veído?
He visto is the present perfect tense, meaning "I have seen." While most regular verbs end in -ado or -ido for their past participle in this tense, the verb ver (to see) is irregular. You just have to memorize that its past participle is visto.
Why does caída have an accent mark on the 'i'?
