The word "律师" is formed by combining the character "律", meaning law or regulation, which is structured with the radical "彳" on the left, often related to conduct, and "聿" on the right, historically linked to writing, with the character "师", meaning master or expert, composed of elements that convey authority or proficiency. In this compound, "律" defines the domain of law, while "师" signifies a skilled practitioner, resulting in a term that directly denotes a lawyer.
