The idiom "run wild" is closely related to "run rampant" in terms of conveying a sense of unchecked movement or behavior. While "run rampant" emphasizes the idea of spreading quickly and without restraint, "run wild" focuses more on the untamed or uncontrolled aspect. This idiom is often used to describe situations or individuals that exhibit a lack of restraint or discipline, behaving in an uninhibited or excessively free manner.

An example of "run wild" could be seen in a group of children let loose in a playground, where they are free to play and move about without any rules or restrictions. Their energy and enthusiasm may cause them to run wild, engaging in energetic and uninhibited activities, such as climbing, running, and playing games without any concern for order or caution.

Similarly, the idiom "run amok" shares similarities with "run rampant." "Run amok" describes a situation where someone is behaving or acting in an uncontrolled, violent, or irrational manner. This idiom originates from the Malay word "amuk," meaning "to attack furiously." In contemporary usage, "run amok" is often used to depict acts of aggression, frenzy, or uncontrolled violence.

A person running amok may exhibit extreme aggression and engage in dangerous or harmful behavior, often targeting others without any clear motivation or purpose. The idiom conveys the idea of someone losing control over their actions and unleashing chaos and violence upon their surroundings, much like when a wild animal goes on a rampage.

Another related idiom is "run riot," which bears a resemblance to both "run rampant" and "run wild" in terms of conveying a lack of restraint or control. "Run riot" is used to describe situations, events, or behaviors that are characterized by unruliness, disorder, or excessive activity.

When something is said to run riot, it means that it is completely uncontrolled, exceeding the usual or desired limits. This idiom can be used to describe various scenarios, such as a child's imagination running riot during playtime, or creativity running riot in an artist's mind. It can also be used to signify disorder or chaos in a more general sense, such as when a protest or demonstration runs riot, leading to violence or destruction.

Lastly, the idiom "run about" is another phrase that shares similarities with "run rampant." While "run rampant" implies unrestricted proliferation or movement, "run about" signifies constant activity, often in a hurried or bustling manner. This idiom is frequently used to describe individuals or groups engaged in frantic or purposeful movement within a limited space.

Imagine a busy marketplace, where vendors are running about, setting up their stalls, attending to customers, and transporting goods back and forth. The constant movement and busy atmosphere create a sense of vitality and energy, with everyone hurrying or scurrying about to accomplish their respective tasks.
