tip

The word centers on the concept of an extremity—whether it is a physical point, a small amount of money "tipped" toward someone, or a small piece of information shared to give an advantage. When used physically (noun/verb), it evokes a sense of precariousness or precision. To "tip" something over implies a shift in balance that leads to instability, while the "tip" of an object is its most distant and often most fragile point. In social and financial contexts, it carries a connotation of gratitude or reward. Unlike a salary, a tip is discretionary, making it a symbol of satisfaction with service. As information, a "tip" feels like a shortcut or inside knowledge. It is less formal than "advice" and often suggests a strategic advantage or a secret that simplifies a task.
