Root Breakdown
Root-derivedFrom error + -ous (full of) = 'full of error.' Where erratic kept the wandering image, erroneous has fully crossed into the 'being wrong' branch: an erroneous belief or assumption is one that has strayed from the facts. The wandering is buried; what's left is plain 'mistaken,' in a formal voice.

Register: erroneous is formal and largely written — it belongs in reports, academic papers, and legal writing. In speech or casual writing you'd just say 'wrong' or 'incorrect.' It typically modifies abstract nouns: erroneous assumption, erroneous belief, erroneous conclusion, erroneous data. You wouldn't call a person 'erroneous' — only their ideas, statements, or results.
