Hi
SKGMSorry for the late reply. I rarely visit this forum these days. Yes, the sentence you mentioned is grammatically correct. However, “Remembered almost as an epic among America’s 12,000 Bosnian Muslims” is not the subject of the sentence. It actually functions as a participial phrase that modifies the subject of the sentence. The main subject of the sentence is "the digging of Chicago's subway tunnels in the early 1900s."
The participial phrase provides additional information about how the digging of Chicago's subway tunnels is remembered by the Bosnian Muslim community. It describes the perception or viewpoint of the subject (how the subject is viewed or perceived by Bosnian Muslims), rather than being the subject itself.
To rephrase the sentence to make it clearer, the structure can be modified:
"The digging of Chicago's subway tunnels in the early 1900s is remembered almost as an epic among America's 12,000 Bosnian Muslims."
The sentence basically says “The digging of some tunnels is remembered as an epic (poem)” or even more concisely “A is remembered as B”. The inverted version of this sentence will be “Remembered as B is A” or “Remembered as an epic is the digging of some tunnels”. Such a structure, in which the subject (the digging…) follows the verb (is remembered) is called Inversion. A similar example:
- Gone are the days when this world used to be a safe place (inverted sentence)
- The days when this world used to be a safe place are gone (normal sentence)
