If you meant to type "caustic" but mistakenly wrote "caucetic", here are some alternate suggestions to correct the misspelling. The correct word might be "caustic" itself, which means sarcastic or corrosive. Alternatively, you could consider "caustics" (a topic in physics related to light reflections), "caucuses" (meetings to select candidates or policies) or "clenetic" (a word that doesn't currently exist).
