Etymology

dubious = dub<doubt> + ious<adjective suffix>

  • dub (from Latin dubius, meaning "doubtful" or "wavering")
  • ious (a suffix forming adjectives, indicating "full of" or "characterized by")

Etymology Origin:
The word "dubious" traces back to the Latin dubius, meaning "wavering" or "uncertain." The root dub- is also seen in related words like "doubt" and "indubitable." The suffix -ious transforms the root into an adjective, conveying a sense of being "full of doubt." Over time, "dubious" evolved to describe not only personal hesitation but also things that are morally or factually suspect.
