Apart vs. A Part
Apart is usually an adverb meaning separated by distance/time or into separate pieces. A part is the article “a” plus the noun “part,” meaning one component or portion of a larger whole. The spacing reflects a real grammatical and semantic difference.
Use “apart” for separation (“The chairs are far apart”). Use “a part” when you mean one component or portion (“She is a part of the team”).
