Antonyms

Grammar Patterns

ethical + noun

it is ethical + to-infinitive

it is not ethical + to-infinitive

Usage Note

Common in questions of moral judgment: 'Is it ethical to…?' Distinguish sense 2 from sense 1 by noting that sense 2 passes judgment (good/right) whereas sense 1 merely describes the domain (relating to moral principles). 'It is ethical' always means sense 2; 'an ethical question' could be either — context determines.

Common Mistakes

That decision was very ethical.
That decision was highly ethical.
'Highly ethical' is the standard collocation; 'very ethical' sounds slightly awkward to many native speakers.
The business is legal but it is not ethic.
The business is legal but it is not ethical.
Confusing the noun 'ethic' with the adjective 'ethical'. Something legal may still not be ethical.

  • ethical brand
  • ethical business
  • ethical fund
  • ethical sourcing
Synonyms
  • responsible

    broader; 'responsible investment' includes financial prudence, not just moral criteria

  • sustainable

Antonyms
  • unethical

    standard opposite for business practices

  • exploitative

    specific to labour or resource practices; stronger negative charge

Grammar Patterns

ethical + noun

Usage Note

Subject is typically a company, fund, brand, or industry. The object of the concern is usually environmental impact, labour conditions, or animal welfare. This sense often appears in compound labels: ethical investment, ethical consumerism, ethical fashion, ethical sourcing. Do not use for individual actions or personal behaviour — that belongs to sense 2.

Common Mistakes

I bought an ethical apple.
I bought apples from an ethical producer.
'Ethical' describes the company or its practices, not the product itself. A product is 'ethically sourced' or 'from an ethical brand'.
The bank claims to be ethical but it still lends to oil companies.
Correct as written.
This structure is fine; just be aware that 'ethical' in this sense is regularly challenged by critics who point out gaps between a company's claims and its actions.

Synonym discussion

Sense: adjective/2

Ethical and moral overlap significantly, but ethical more often refers to a system of professional or societal standards (an ethical dilemma for a doctor), while moral tends to describe personal beliefs (a moral objection to violence). Principled describes someone who acts consistently according to strong personal values, regardless of consequences — a principled politician votes against her own party when she disagrees. Righteous carries a much stronger, often negative connotation of self-certainty and indignation (a righteous tone of voice). Virtuous has an old-fashioned, character-focused feel, associated with personal purity rather than professional conduct. For everyday use: choose ethical when talking about professional or business standards; choose principled for personal integrity; avoid righteous unless you intend criticism; and treat virtuous as dated.

Etymology

GreekLatinFrenchEnglish

Ethical entered English in the late 1500s from Latin ethicus, which came from Greek ēthikos (relating to character or custom). The Greek root ēthos means 'character, nature, or custom'. The word was originally used in philosophy to describe the study of character and how people should live, and later broadened to cover moral conduct in all areas of life.
