Example from page 75 of Frederick Schauer’s Thinking Like a Lawyer:
But what of mandatory authorities? Are they as “binding” as the traditional terminology suggests? The answer depends on what is meant by “binding,” and it turns out that speaking of “binding” authority can be just as misleading as speaking of “persuasive” authority.
What are the similarities and differences between what about and what of? I see that the definitions below are worded differently, but I don’t see any intrinsic differences — which I still suspect must exist.
what about 1a. does that include (someone) : how about (someone)
1b. how does that affect (someone or something) :
2. used to make a suggestion about what could be done
3. used to ask someone to tell you something in response to the thing that you have just said
what of 1. formal how does that affect (someone or something)
2. why does (something) matter
