Intransitive verb and Ichidan verb
にる
お前が彼女の兄貴だって？嘘つけ！全然似てないじゃねえか。
Are you telling me that you’re her brother? Liar! You look nothing alike.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means resemble so the verb vocab version is to resemble.
What are you trying to resemble?? Is that... oh no. A knee (に) face resemble surgery, where you make your face look like your knee and vice versa? Do you know how dangerous that surgery is?
