I have a punctuation question. Does Students Corner require an apostrophe?
Making the distinction between possessive and descriptive nouns will help you to decide when an apostrophe should be used and when it should not.
In most cases, when a noun is descriptive and ends in s, no apostrophe is necessary (i.e. a savings bank, a United Nations summit, an estimates meeting). In these examples, the nouns ending in s serve as describers rather than possessors. Usually, other words are understood but not stated (i.e. a bank for savings, a summit by/for the United Nations, a meeting for estimates). Since, in your example, the noun "Students" is a describer (i.e. a corner for students) and not a possessor, no apostrophe is required.
But if you wish to emphasize that the corner belongs to students, you need to add an apostrophe after the s: Students' Corner.
