A more thorough explanation:

Elements of a case refer to the essential parts of a legal claim or cause of action that a plaintiff must prove to win a lawsuit. In other words, they are the building blocks of a legal claim that a plaintiff must establish to succeed in court.

For instance, in a negligence claim, the elements that a plaintiff must prove are:

• The defendant owed a legal duty to the plaintiff
• The defendant breached that duty
• The plaintiff suffered an injury
• The defendant's breach caused the plaintiff's injury

These elements must be proven by a preponderance of the evidence, which means that it is more likely than not that the plaintiff's version of events is true.

When a plaintiff files a lawsuit, they must identify the cause of action and allege the specific acts of the defendant that violated the law. For example, in a negligence claim, the plaintiff would allege that the defendant had a duty to act with reasonable care, that they breached that duty by acting negligently, that the plaintiff was injured as a result, and that the defendant's negligence caused the plaintiff's injuries.

Overall, the elements of a case are the essential components that a plaintiff must prove to win a lawsuit, and they vary depending on the type of legal claim being pursued.
