Chorus

While researching the chorus, I found it is used as a type of narration. It is usually a small group of people or person who comments on the main action in a dramatic tone. They usually do the prologue and epilogue.

this is the chorus:

"Two households, both alike in dignity

(In fair Verona, where we lay our scene),"

I translate this as : 2 families; The Capulets and Montagues, both similar in dignity. Dignity meaning the state or quality of being worthy of honor and respect, I found this on Google and also saw similar lines in Ryan A's Post!

Dignity also can mean a sense of pride in ones-self. So in this case both families think very highly of themselves. The part in brackets is telling you that the play/ story takes place in Verona, Italy. 

" From ancient grudge break to new mutiny,

Where civil blood makes civil hands unclean."

I think this means a really old grudge, or rivalry between the families turns into a whole new kind of violence that it progressing in a bad way. And because it is a whole new level of resentment, they are getting people involved that  aren't even a part of the grudge in the first place. (for example: Mercutio was neither a Montague or Capulet but found himself in the middle of the feud.)

"From forth the fatal loins of these two foes

A pair of star-crossed lovers take their life,"

Decedents or Children from the two unfortunate families that are enemies, become lovers, and take their own life or commit suicide.

"Whose misadventured piteous overthrows

Doth with their death bury their parents' strife."

The unfortunate incident created a removal of power from both families (meaning both families had something taken away from them) Their death ended their parent's conflict.

"The fearful passage of their death-marked love

And the continuance of their parents' rage,"

The frightening process of their death due to love, and angry parents.

"Which, but their children’s end, naught could remove,

Is now the two hours' traffic of our stage—"

The anger of the parents can only be resolved by the death of their children, this will be the 2 hours you will watch on the stage.

"The which, if you with patient ears attend,

What here shall miss, our toil shall strive to mend."

If you listen carefully and are patient, what we didn't say here we will work hard and explain the rest. ( meaning what ever they didn't say will be explained on the stage in the 2 hours you watch it.)
