協力する

Let's learn how to use the Japanese verb 協力する (きょうりょくする - kyouryoku suru), which means "to cooperate" or "to collaborate." This is a really useful verb, especially if you're working with others or talking about teamwork. It's a CEFR B1 level word, so it's something you'll encounter quite often.

協力する is a combination of the noun 協力 (kyouryoku - cooperation/collaboration) and the verb する (suru - to do). This is a common pattern in Japanese where you take a noun and add する to turn it into a verb. Think of it like saying "do cooperation" in English, but it naturally means "to cooperate."

§ Basic Usage

The most straightforward way to use 協力する is to simply state that someone or something is cooperating. You can use it with a subject and optionally an object indicating what is being cooperated on or with whom.

Hint: We cooperated.

Hint: They are cooperating on this project.

§ Who are you cooperating with? (～と)

To specify *who* you are cooperating with, you'll use the particle と (to). This particle indicates association or accompaniment, which is perfect for expressing "with someone."

Hint: I cooperated with the team to solve the problem.

Hint: They are cooperating with each other.

§ What are you cooperating for/on? (～に / ～のために)

To express *what* you are cooperating for or towards, you can use the particle に (ni) or のために (no tame ni).

Using に (ni)

The particle に can indicate the purpose or objective of the cooperation.

Hint: We will cooperate to achieve the goal.

Using のために (no tame ni)

のために explicitly means "for the sake of" or "in order to," making the purpose very clear.

Hint: Let's all cooperate for the company's development.

§ Making a Request: Please Cooperate

To politely ask someone to cooperate, you can use the て-form of 協力する (協力して - kyouryoku shite) followed by ください (kudasai).

Hint: Please cooperate with us.

Hint: We ask for your cooperation with the investigation. (Literally: Please give us cooperation regarding the investigation.)

Here are a few more things to keep in mind:

• 協力的な (kyouryokuteki na): This is an adjective meaning "cooperative."

協力する is a versatile verb. The key is to remember the particles: と (to) for who you cooperate with, and に (ni) or のために (no tame ni) for what you're cooperating for. Practice these sentence patterns, and you'll be using 協力する like a pro in no time!
