お見それしました。

The phrase 'お見それしました' (Omisoreshimashita) is a polite and humble Japanese expression used to apologize for misjudging someone or something, often accompanied by an admission of admiration or newfound respect. Its roots can be traced back to the Edo period (1603-1868) and earlier, reflecting the deep-seated cultural values of humility, respect, and proper social conduct in Japan. The core of the phrase lies in the verb '見損なう' (misonau), which means 'to misjudge,' 'to mistake,' or 'to underestimate.' This verb itself is a combination of '見る' (miru), meaning 'to see' or 'to look,' and '損なう' (sonau), meaning 'to harm,' 'to spoil,' or 'to fail.' Thus, '見損なう' literally implies a 'failure in seeing' or a 'spoiling of one's perception.' The prefix 'お' (o-) is an honorific prefix used to show respect and politeness, often attached to nouns and verbs to elevate the social standing of the person being addressed or the action being performed. In this case, 'お見損なう' (omisokonau) would be a more polite form of '見損なう.' The suffix 'しました' (shimashita) is the past tense, polite form of the verb 'する' (suru), meaning 'to do.' When appended to a noun or a verb stem, it forms a polite past tense, indicating that the action has been completed. So, 'お見損ないしました' (omisokonai shimashita) would mean 'I politely did the action of misjudging.' Over time, the phrase evolved into 'お見それしました,' with '見損なう' shortening to '見それる' (misoreru) in this specific context, while retaining its original meaning of misjudgment. The 'る' ending of '見それる' is then dropped, and 'しました' is added to form the polite past tense. This kind of linguistic evolution, where verbs are slightly altered for ease of pronunciation or specific idiomatic usage, is common in Japanese. The nuance of 'お見それしました' goes beyond a simple apology for a mistake. It often carries a sense of pleasant surprise and admiration. When someone uses this phrase, they are not just saying 'I was wrong about you'; they are also implicitly acknowledging that the person they misjudged has proven themselves to be more capable, intelligent, or impressive than initially thought. This makes the phrase a powerful tool for expressing newfound respect and humility in social interactions, emphasizing the importance of not judging a book by its cover.
