What does principled mean?
Principled describes a person, decision, or approach guided by consistent moral or intellectual standards. The word is especially associated with integrity: a principled person continues to act according to important beliefs even when doing so is difficult, unpopular, or less profitable. It can also characterize policies and decisions that follow stated rules rather than expediency or short-term advantage. The adjective is usually approving and formal, with the positive sense that the behaviour reflects both conviction and consistency. In this respect, it differs from words such as careful or reasonable, which describe the quality of judgment without necessarily implying a moral foundation. Principled conduct is often distinguished from merely following convention, since the word suggests adherence to principles that may require deliberate resistance to pressure. The term is consequently useful when describing actions that remain faithful to a person’s values, especially in public life, professional ethics, and disputes over fairness.
Having or showing firm moral principles, especially in the face of pressure, temptation, or compromise.
"Her principled refusal to accept a dishonest settlement earned both admiration and criticism."
Generally approving; commonly implies moral integrity and consistency over time.
Derived from or consistently guided by an underlying rule, value, or principle.
"The committee adopted a principled interpretation of the regulations that applied equally to every applicant."
Used of decisions, policies, arguments, and approaches as well as people.
Calling someone principled says more than merely praising their judgment: it suggests that their values still hold when doing the easy thing would be tempting.

Where does principled come from?
Principled was formed in the early 17th century from principle, with the suffix -ed meaning “having” or “characterized by.” Principle comes through Old French from Latin principium, “beginning” or “foundation,” a word associated with the idea of a first principle or underlying rule. The related Latin princeps also gave English principal, meaning chief, as well as words such as princely and princess.
