Learn Italian: Cerchiamo un esperto con questa competenza. - We are looking for an expert with this skill.

In Italian, the verb cercare already means "to look for" or "to search for". You do not need to add a preposition like per after it. You just connect the verb directly to the object, as in cerchiamo un esperto (literally: "we seek an expert").

Why is it un esperto without an apostrophe, even though the noun starts with a vowel?

An apostrophe is only used when dropping the final "a" from the feminine article una (for example, un'esperta). Since esperto is a masculine noun, it uses the standard masculine article un, which never takes an apostrophe.

How does the noun competenza tie into the difference between sapere and conoscere?

Competenza translates to a specific skill, ability, or area of expertise. If you want to describe someone actively using a skill with a verb, you must use sapere (meaning "to know how to do something"), rather than conoscere (which is used for being familiar with a person, place, or thing).

Why do we use questa instead of questo here?
