I'm putting this as a separate question though I already asked it here. That's because either I will learn more about using the adjective good or I'll know more about how a phrasal noun which refers to some grief takes a positive adjective?
What is good in Good Friday? An adjective, isn't it? But then if it's really good, how does it justify its meaning? As Good Friday is certainly a very sad day to lose such a person of God. Where's the goodness in that? Is there any positive adjective that's used this way forming a noun-phrase which actually means exactly opposite to that (A bad Friday?, indeed a bad day as we lost him). I'm choosing the tag 'Word Choice' here.
