X + と共に + Y as “Y along with X”
The phrase と共に (とともに) can be translated to “with, along with, together with, as, as well as, while, when, etc.” In its usage as a grammar pattern, it adopts one of several nuances depending on the context of the sentence. In general, the main three nuances that と共に carries are:
1.) Y together with X
2.) Y at the same time as X
3.) as something, X, changes, something else, Y, changes with it
Grammatically, the X + と共に + Y grammar pattern is used with the Dictionary-Form of verbs, nouns and い-adjectives as just the words themselves, and な-adjectives with the respective Plain-Form conjugation of the phrase である immediately after them and before と共に.
