Perhaps I could have been more clear. Having the legal right to be something and actually being that thing are different. I obtained the legal right to practise law in 1976 when I took and passed the bar exam. It took some years of actual practise before I could credibly claim to be a lawyer.

On television, in advertisements, and from our friends, we often hear reference to “lawyers” and “attorneys.” Despite the ease of categorizing these two words as synonyms, they do in fact mean different things. The difference is only slight, but it matters a great deal to state bar associations, particularly in the investigation and prosecution of unauthorized practice of law cases. However, practically speaking, the terms have become interchangeable in the United States.
A lawyer is simply one who is trained in the law. They may or may not provide legal guidance to another. Thus, anyone who has attended law school in the United States can consider themselves a lawyer. However, until they pass the bar exam in the jurisdiction in which they intend to work, the method by which they use their lawyering skills is limited. For example, a policy advisor or consultant to the government, who attended law school, is technically a lawyer and may offer his skills in the course of his work, but he must not cross the fine line into providing legal representation.
An attorney or attorney at law is also a lawyer. They have attended law school and presumably “practice” the study of law as a career. However, attorneys by definition have passed a bar examination and have been admitted to practice law in the particular jurisdiction. They may go beyond the realm of lawyer and provide legal representation to an individual. The relationship is more than merely providing the factual state of the law and delves into providing strategy for the client’s needs in reference to the law. An attorney can also appear in court and other settings on behalf of a client. An attorney is also a lawyer, but a lawyer may not necessarily be an attorney.

Though technical differences exist, practically speaking, only a lawyer would know the difference between lawyer, attorney, barrister, solicitor, or the limits on using esquire. The general public can probably rest easy in a world of synonym, as long as they ensure the lawyer handling the case is also an attorney.
