verb

To make something legal, acceptable, or officially approved. It can also mean to make an action or idea seem acceptable.

  • The law legitimized the new political party.
  • He tried to legitimize his decision with facts.
  • That excuse does not legitimize rude behavior.

Adinary Nuance

Legitimize is stronger and more official than justify. You use it when something becomes legal, approved, or accepted by authority. It is also different from validate, which is often about confirming that something is true or correct. If you mean “make seem okay,” legitimize can sound more formal and serious.
