Regarding restrictive and nonrestrictive adjective clauses, I basically know how to use them.
However, I am kind of curious about the abbreviation usages of nonrestrictive adjective clauses.
For instance: I know these are right
She is the girl goofing around last night = she is the girl who goofed around last night
This is her famous series called Harry Potter = this is her famous series which is called Harry Potter.
They are abbreviations of restrictive adjective clauses.
Then, my question is how the abbreviations of nonrestrictive adjective clauses work.
Do they work like this? For example:
This is J. K. Rowling's most successful series, called Harry Potter.
He is my dad, cleaning the room
John is my big brother, studying in Physics.
Are them equal to the sentences below?
This is J. K. Rowling's most successful series, which is called Harry Potter.
He is my dad, who is cleaning the room
John is my big brother, who studies in Physics.
Can I just add a comma and a space to abbreviate nonrestrictive adjective clauses? Or actually, there are no that kind of usages?
