Usage

What does collaborate mean? Collaborate means to work together, especially on a goal or shared project. Collaborate is often used in a positive context to refer to two or more parties successfully working together on professional or artistic projects. It often implies more than just cooperation. When two or more people collaborate, they often share and develop each other’s ideas. The act of collaborating is called collaboration. Such a joint effort can be described with the adjective collaborative. People who collaborate are called collaborators. Collaborate can also be used in a much more specific way meaning to cooperate as a traitor with enemy forces in one’s own country. This is much less commonly used than its general sense. Example: The two musicians, who usually have very different styles, collaborated on the groundbreaking new album.

Explanation

When you work together on shared goal, you collaborate. If you don't just split a project up evenly but work together on creating solutions, you collaborate. Inside the word you see co-labor, or "working together." Cooperation is simply splitting up the work and getting it done. Collaboration is when you brainstorm, create, and share possible solutions. During World War II, however, Nazi collaborators were sharing ideas with the wrong side. In today's pop music scene, collaboration means featuring a guest star on a record, and it's often a surefire way to boost sales.
