A possessive shows ownership. If a janitor has a house, we'd say it was the janitor's house. Just add an apostrophe + s to any regular singular noun, then add what that noun owns (or possesses) to get the possessive form. Here are a few examples: the janitor's bucket, the janitor's son, the janitor's uniform. Here are some others: The teacher's smile was sweet. I saw the robin's eggs in a nest. When the boy's shoelaces came loose, he tripped on Joe's bookbag. Look at the nouns that follow the possessive form. Ask yourself, "Who owns it?" The answer is~ the teacher, the robin, the boy, Joe. Or, for your question, the janitor. I just heard the janitor's keys in the hall. Who owns the keys? The janitor. The apostrophe is added AFTER the owner and is followed by an "s" for a singular, regular noun.
