Normally, the sinuses produce mucus and drain it through small openings into the nasal passages. But in rhinosinusitis, as the disorder is technically known, swelling in both the nose and sinuses blocks that drainage. The result is a stuffed-up nose and an endless outpouring of green or yellow mucus.
The semicolon or semi-colon (;) is a punctuation mark that separates major sentence elements. A semicolon can be used between two closely related independent clauses, provided they are not already joined by a coordinating conjunction. Semicolons can also be used in place of commas to separate items in a list, particularly when the elements of that list contain commas.
Between independent clauses when a coordinating conjunction is omitted. Most commonly, the semicolon is used between two independent clauses (i.e., clauses that could stand alone as separate sentences) when a coordinating conjunction (for, and, nor, but, or, yet, so) is omitted.
