訴追 (そつい) means "prosecution or impeachment," primarily in a legal context. Both `訴` (ソ) and `追` (ツイ) are standard On'yomi readings. `訴` means to appeal or sue, and `追` implies pursuing or chasing. The compound denotes bringing a charge or proceeding against someone. Misreadings like `そひ` and `すいつ` incorrectly apply alternative On'yomi or phonetic similarities to `訴` and `追`.

訴追 (そつい) は「罪を問い、法の裁きを求めること」を意味する法律用語です。「訴」（ソ）も「追」（ツイ）も標準的な音読みです。誤読の「そひ」や「すいつ」は「訴」や「追」の読み間違い、「そい」は音の混同による誤りです。
