"Clad" is neither a verb nor a noun, Shakespeare. It's an adjective. "Cladding" is a noun.
WHAT do YOU KNOW ABOUT Shakespeare? Most people have not read his literature and won't write like him these days.
HERE, IT IS MOSTLY referring to speaking today.
In general, among people talking to each other, that was what it was said.
In some cases, people can put that in writing too, or as poetry (the dictionary may not illustrate all in full).
What do you think you are, as if people would have to write like
Shakespeare? Shakespeare things tend to be long opera shows, poetry things recitals anyway, as not quite applicable for scientific and technological subjects, as well as people-to-people communication verbiage nowadays.
That is not suitable for today's society, including in formal and business writings.
