A more thorough explanation:

Definition: Insinuatio (in-sin-yoo-ay-shee-oh) is a legal term that refers to information or suggestion.

For example, in a court case, a lawyer might use insinuatio to suggest that the opposing party is guilty of a crime without actually making an accusation. This can be a powerful tool in legal arguments, as it allows the lawyer to plant a seed of doubt in the minds of the judge or jury without making a direct accusation.

The term "ex insinuatione" was often used in the past to indicate that a statement was made based on information and belief. This phrase is the precursor to the modern "on information and belief" that is commonly used in legal documents today.

Overall, insinuatio is a term that refers to the use of suggestion or implication in legal arguments. It can be a powerful tool for lawyers, but it must be used carefully to avoid making false accusations or misleading the court.
