Mistakenly describes something someone did based on a wrong belief or wrong information — they thought one thing was true when it wasn't, and acted on that wrong idea. It usually comes before the verb it describes: "he mistakenly believed the store was closed" means his belief was wrong, and that's why he acted the way he did. It has a gentle, forgiving tone — it explains an honest error, not a deliberate lie.
錯誤地、誤以為地（因為搞錯了才做某事）
