Layman means an individual with little or no knowledge of a particular subject, for example, "a computer layman".
The meaning comes from the religious milieu when it referred to the member who did not have sufficient knowledge for certain functions within the religious organization to which he belonged.
In the Catholic Church, lay people are Christians who are not part of the clergy, that is, they are not ordained nor are they part of the ecclesiastical hierarchy, but actively participate in activities related to the Church.
The term "layman" is derived from the Latin "laicus" whose origin comes from the Greek "laikos". It is synonymous with "lay" or "lay", that is, who does not belong or is not subject to any religion. For example: lay or lay teaching.
lay judge
In the legal field, "lay judge" means the individual who does not have a magistrate's degree but has the functions of an auxiliary justice. A lay judge can, for example, conduct conciliation hearings, prepare the pre-trial process and even draft a sentence proposal. However, all proposals will be judged by a togado judge (magistrate).
In criminal law, the lay judge has no decision-making power and is prevented from issuing any sentence, this function being the responsibility of the magistrate. The term layman indicates that the individual has no knowledge of magistracy.
