A more thorough explanation:

Definition: Submit means to give something over to the discretion or judgment of another person or entity, or to present something for determination.

For example, in a legal context:

• To submit evidence: This means to present or introduce evidence in a court of law. For instance, a lawyer might submit a document as evidence in a trial.
• To submit a case: This means to finish presenting evidence or an argument in a hearing or trial and give the matter over to the judge for a decision. For example, a lawyer might submit a case to a judge after presenting all the evidence and arguments.

These examples illustrate how the term "submit" is used in a legal context. When someone submits evidence or a case, they are essentially giving it over to the decision-making authority of a judge or other legal entity. This means that the judge will use their discretion and judgment to determine the outcome of the case based on the evidence and arguments presented.
