Have yet to read it, but here’s the topic:

よく? Unsure of meaning

Hello! This is my first ever post! I’m having some trouble translating one word from this wanikani sentence: よく! The context sentence is: 二人の姉妹はとてもよくにています. Now, I know wanikani just gives you the translation, but I like breaking down the sentence so I can learn new grammar and other vocab words. I’ve looked on Jisho and eventually friend google translate, and I just don’t know what this word means! Please help!
