Apart or A Part: What's the Difference ?

Apart and a part are both correct, but they have different meanings. Apart means separated, away from something, or into pieces.

The Origin of Apart or A Part

The word apart comes from the Middle English phrase a part, which originally meant “to one side.” Over time, the two words joined together to form the single word apart, giving it the meaning of being separated or divided.

The phrase a part kept its original meaning of “one piece” or “one member of a whole.” Because both forms share the same history and pronunciation, writers often confuse them. Today, English keeps both spellings because each has its own meaning and grammatical role.
