Learn Spanish (Latin America): Recientemente visitamos una exposición interesantísima. - We recently visited a very interesting exhibition.

Just like adding "-ly" to an English adjective makes an adverb, adding -mente does the same in Spanish. Since the adjective reciente ends in an "e", we just attach -mente to the end to get recientemente (recently). It is a great time word to show an action happened in the near past.

Wait, doesn't visitamos mean "we visit" in the present tense?

It means both! For regular -ar and -ir verbs, the "we" form is exactly the same in the present tense and the past (preterite) tense. You have to look at context clues to know which one it is. Here, the time word recientemente tells us this is the past tense: we visited.

What does the -ísima ending do in interesantísima?

Adding -ísimo or -ísima to an adjective is a common way to say "very" or "extremely" without using the word muy. The base adjective is interesante. We drop the final vowel and add -ísima to make interesantísima (extremely interesting). It ends in -a to match the feminine noun exposición.
