見てぬふりをする

The phrase '見てぬふりをする' (mite-nu furi o suru) is a combination of several linguistic elements in Japanese. 1. **見て (mite):** This is the te-form of the verb '見る' (miru), meaning 'to see' or 'to look.' The te-form is versatile and can be used to connect verbs, indicate a state, or form compound expressions. 2. **ぬ (nu):** This is an archaic negative auxiliary verb, equivalent to the modern 'ない' (nai). It attaches to the imperfective (mizenkei) form of verbs. In this case, '見ぬ' (minu) means 'not see' or 'unseen.' While 'ぬ' is largely replaced by 'ない' in modern conversational Japanese, it persists in certain fixed expressions, classical literature, and more formal or literary contexts, often adding a nuanced or slightly archaic flavor. 3. **ふり (furi):** This noun means 'pretense,' 'show,' 'appearance,' or 'feigning.' It is often used in the pattern '～のふりをする' (～ no furi o suru) meaning 'to pretend to be ～' or 'to feign ～.' 4. **を (o):** This is the direct object particle, marking 'ふり' (furi) as the direct object of the following verb. 5. **する (suru):** This is a very common and versatile verb meaning 'to do,' 'to make,' or 'to perform.' When combined with a noun like 'ふり,' it forms a compound verb meaning 'to pretend' or 'to feign.' Putting it all together, '見てぬふりをする' literally translates to something like 'to do the pretense of not seeing' or 'to make as if one does not see.' Over time, this combination of 'not seeing' (見てぬ) and 'feigning' (ふりをする) naturally evolved to convey the meaning of intentionally overlooking something, feigning ignorance, or pretending not to notice. The use of the archaic 'ぬ' gives the expression a somewhat classical or idiomatic feel, implying a deliberate act of non-acknowledgment rather than a simple failure to see.
