We all know that an appositive is a noun or noun phrase that renames another noun right beside it. When I saw this line "The law will take effect starting the month of December", somehow I felt the line can also be thought of as "The law will take effect starting the month December" where month and December are in an appositive relation.
That bears the question of this post: Is "The month of December" a type of appositive?
Here is another example on the Internet:
Following the acquisition of Specialty Fasteners & Components (“SFC”) by Clarendon in 2014, the business will now trade under the unified name of Clarendon Specialty Fasteners, with effect from February 1st, 2017.
,where "the unified name of Clarendon Specialty Fasteners" can be thought of as "the unified name Clarendon Specialty Fasteners" or "the unified name, Clarendon Specialty Fasteners", in which case the word "of" can be omitted.
But I got confused because I thought the only way to use the word "of" is something like these lines:
The function of screws. (Screws and function are not the same thing)
A friend of mine.
"The month of December" (where December and month are the same thing) feels like something different from the above two lines and I could only understand it by thinking of it as an appositive structure. Am I thinking this right?
And how do you explain this sentence:
The company follows the guideline of "Customers First".
Is that an appositive structure, or the same structure as in "The function of screws"?
