'some kind of' vs 'of some kind'

[Edison_Chen_e_c]

What is the difference between the two?
some kind of book
a book of some kind

Thanks in advance.

Nothing that I can discern here. 'Some kind of' also has a casual exclamatory meaning: Wow! That was some kind of adventure story! It had me on the edge of my seat for the last 100 pages!

Hi, MM

I know that there is a set expression: of a kind, isn't there?
Which means "in bad condition".
Like: I was mad at him because he'd presented me an umbrella of a kind on my birthday

What do you think?

I seem to recall such; I don't use it much. Maybe another member can offer you more opinion on it.

I'm not sure 'of a kind' is used to mean 'in bad condition' necessarily, but it can have the sense of 'indifferent (or maybe even mediocre/disappointing) quality':

of a kind

Other similar set phrases with a different meaning are:

be one of a kind
be two of a kind

Thanks all, I understand it now.

of a kind means disappointing quality
