What does ethical mean?
"Ethical" is an adjective with two closely related meanings: it can describe anything pertaining to moral principles or to ethics as a field of study — an ethical question, an ethical framework — or it can describe behaviour that is itself morally right, as in an ethical business practice. The word derives from Greek "ēthikos," meaning relating to character or custom, which passed into Latin and then into English by the seventeenth century. In everyday use it appears constantly in discussions of medicine, journalism, business, and science, where people weigh the ethical dimensions of difficult decisions; calling a person or company ethical is a strong compliment suggesting integrity and principle. Its natural opposites include "unethical" and "immoral." Because it overlaps with "moral," writers often use "ethical" for codes of professional conduct and systems of reasoning, while "moral" leans toward personal conscience — though in ordinary speech the two are frequently interchangeable.
Relating to moral principles or the branch of knowledge concerned with them.

"Ethical" and "ethnic" differ by just two letters — but one judges your morals while the other describes your heritage.

Etymology of ethical
"Ethical" traces back to the ancient Greek "ēthikos," meaning "relating to character" or "of one's disposition," derived from "ēthos," the Greek word for character or customary way of behaving. The term passed into Latin as "ethicus" before entering English in the early seventeenth century, initially in scholarly and philosophical contexts. Its Greek root also gives us "ethics" and "ethos," making these close cognates within English.
