Not completely. Ancient Greece had
ethos and
logos. The etymology of the English
ethics derived from ethos but the definition is different.
* ethos describes character and conduct
* logos describes pleas and persuasive speech. This is the etymological root of the English legal.
Ethics does deal with moral character and is a branch of moral philosophy but is more specific than mere right vs wrong as the word itself is more concerned with practical application. Ethics is typically concerned with decisions and alignment to rules or codes of conduct. In this way ethics has the most value in a legal and reputational contexts. It is safe to think of ethics as an alignment to rules that may be explicitly stated or commonly accepted.
Morals on the other hand are a broad term concerning right and wrong in accordance with societal norms and a personal value system.
These terms can be at odds when a person is asked to follow rules whose violation bears legal consequence but such conduct defies their personal values, such as: loyalty, confidentiality, or religious canons.
