自惚れ (うぬぼれ) is a jukujikun reading, where the kanji combination is read with a native Japanese word. 自 means 'self' and 惚れ means 'to be infatuated.' Direct On'yomi/Kun'yomi combinations like じほれ are wrong, as is the verb form うぬぼる. It signifies 'conceit, vanity, or excessive self-admiration,' a feeling of being excessively charmed by oneself.

自惚れ（うぬぼれ）は熟字訓で、個々の漢字の音訓では読めません。自は「自分」、惚れは「惚れる」を意味します。じほれのような直読や動詞形うぬぼるは誤り。自己を過度に評価し「うっとりすること」を指します。
