Apostrophes, commas and semicolons fall under the "punctuation" category. Is there a subcategory, however, that distinguishes between apostrophes and commas/semicolons/colons...?
Edit: hyphens would go with apostrophes and question marks, dashes, etc. with commas. Basically, I'm trying to distinguish between the punctuation that puts a term together (e.g. "I'm", "k-means") and the rest, which don't characterize single terms (like commas, question marks, etc.).
