[html5] "Block" and "inline"

[Micky Hulse]

Hello,

Just looking for clarification on the below two paragraphs taken from
the book "HTML 5 for Web Designers":

[[

CONTENT MODELS

Previous flavors of markup divided elements into two categories:
inline and block. HTML5 uses a more fine- grained approach, dividing
elements into a wider range of categories.

Inline elements now have a content model of “text-level semantics.”
Many block level elements now fall under the banner of “grouping
content”: paragraphs, list items, divs, and so on. Forms have their
own separate content model. Images, audio, video, and canvas are all
“embedded content.” The new structural elements introduce a completely
new content model called “sectioning content.”

]]

Am I the only one that finds the above two paragraphs confusing? I
would love some clarification.

Does the above translate to this(?):

Inline = Text-level semantics
Block = Grouping content
Images, audio, video, and canvas = Embeded content

Can I still call things block and inline?

Sorry if stupid question(s)... I just want to be sure I am using the
right lingo when talking about HTML5. :)

Thanks so much!

Cheers,
Micky
