* Origin: It comes from the Old French word "esquier," meaning "shield-bearer." Originally, it was a title used for knights and gentlemen who served as attendants to noblemen.
* Modern Usage: Today, "Esq." is primarily used in the United States and some parts of Canada as a courtesy title for lawyers, particularly in legal documents and formal correspondence.
* Purpose: It's a way to show respect and formality in addressing a lawyer.
* Alternative: "Attorney" or "Lawyer" are more commonly used in everyday conversation.
Important Note: It's not appropriate to use "Esq." for everyone. It's specific to lawyers, and it can even be seen as pretentious if used improperly.
