幾可亂真 means something along the lines of "near identical to the real thing".
幾 = 幾乎 almost
可 = 可以 be/like
亂真 = near identical to the real object
Correct me if some of my understanding above is wrong. My question is what does 亂 mean? In
亂真 it seems 亂 is an adjective describing 真, so I can postulate 亂 means strongly/very. But the word 亂 itself means a mess/disorder, so I'm confused as to what it really means in 亂真. Thanks for the help.
