as the former imperial palace was known

Hi guys~

"The Forbidden City, as the former imperial palace was known, is stil at the center of the metropolis, and the basic Ming dynasty construction of the city on a northsouth axis can still be traced through it."

I don't understand the sentence "as the former imperial palace was known".

 

[Nunty]

It means that the former imperial palace (the place that used to be the imperial palace) used to be (was once) called (known as) "the Forbidden City".

 

[SRPGgamer]

so "as" = "like" right?

 

[Nunty]

so "as" = "like" right?

Yes, exactly.

so "as" = "like" right?

Almost, but not quite. While the meanings are similar, only "As" is grammatically correct in this sentence; to use "like" here would be incorrect.
