Is this proper use of a semicolon?

Actually the correct punctuation here is the colon (:) rather than the semicolon; one is a direct correlation of the other without being separate complete clauses.

A dash is also correct, and perhaps even better.

Semicolons can be used to give heirarchy to lists: one, two, three; A, B, C.

EDIT: Yours still reads better.. Stick with it!

Yes; that works.

I might have phrased the sentence as follows, but this is a matter of personal preference:

Filth, disease and overcrowding; the plight of inhabitants in the English city of Manchester during the Industrial Revolution.

Both say the same thing.. so..

Hope this helped..

specific, that is. the two aspects of the sentence are finished, appropriate, stand-on my own sentences: until eventually now the trial, Dill had no longer seen bigotry. Atticus grow to be accepting of easily anybody and the lynch mob grow to be stopped via teenagers innocence.

particular, that's. the two areas of the sentence are finished, appropriate, stand-on my own sentences: in the previous the trial, Dill had no longer seen bigotry. Atticus replaced into accepting of anybody and the lynch mob replaced into stopped by skill of childrens innocence.

It doesn't pass the however test. saying however after clause doesn't make sense. Three adjectives make a lossy clause, so make a better dependent clause and it might work.

Yes, lovely :-) Nice to see one, they seem to be going out of fashion!

Yes, it seems to work there fine.

I would say so.

But, what's ur conjuction?!?
