Learn Italian: La Terra esisterà sempre, ma esploreremo un altro pianeta. - Earth will always exist, but we will explore another planet.

Esistere is a regular -ere verb. To make it future tense, we drop the final -e from the infinitive to get the stem esister-, then add the third-person singular ending -à because the subject is La Terra (it). This gives us esisterà.

Why is the future tense of esplorare spelled esploreremo and not "esploraremo"?

For regular -are verbs in the future tense, the a in the infinitive ending changes to an e. This means the stem esplorar- changes to esplorer-. We then add the "we" ending -emo to make esploreremo.

Wait, pianeta ends in -a. Why does it use the masculine word un?

Pianeta is a common exception! Even though it ends in -a, it is actually a masculine noun. That is why it takes the masculine article un and the masculine adjective altro. In the plural, it becomes i pianeti.

Why is there no apostrophe in un altro?
