Generally, definite articles are NOT used before names of organizations:
* United Nations
* Apple Inc.
* The University of California, Berkeley (although it's part of the name, it is used to distinguish it from other University of California campuses)
Exceptions:
* The Red Cross
* The World Bank
* The American Red Cross (using "the" for the specific branch of a broader organization)
When using definite articles with organization names is appropriate:
* For clarity: If you are talking about a specific instance or branch of an organization, you may use "the." For example, "I visited the local library."
* For emphasis: You may use "the" to emphasize a particular organization, especially if it's well-known or if you are contrasting it with other organizations. For example, "The United Nations is an international organization."
* When the organization's name includes "the": As mentioned above, "The Red Cross" and "The World Bank" are examples.
In most cases, it's best to avoid using "the" before the name of an organization unless it's absolutely necessary for clarity or emphasis.
Important Note: It's always a good idea to check the official style guide or documentation for specific organizations to see their preferred usage.
