A Part of vs. Part of

Use part when talking about an integral element that belongs to something and is essential to its nature. Use a part when talking about one of several or many equal units of something bigger — combined all together, these units make up the whole.

A Part of vs. Part of Tip

If you can separate a part from a whole, use a part.
