Hey All,
Lots of good discussion on this one, but also some fundamental mistakes that need to be addressed.
1. As she was leaving the bank,Evelyn’s purse was stolen . Is it correct ?
2. Evelyn’s purse was stolen,As she was leaving the bank, . Is it correct ?
There are two issues here: modifiers and pronouns. The bigger problem is pronouns. In both of these sentences, the pronoun "she" is supposed to be referring to Evelyn, but believe it or not, Evelyn is not in either of these sentences!
Take a closer look at "Evelyn's purse". Purse is a noun, and Evelyn's is a possessive adjective. A pronoun CANNOT refer to a possessive adjective. It's called a pronoun because it stands in for a NOUN. Because of this, neither of these sentences are right.
Furthermore, sentence one has a prepositional phrase acting as modifier, so whoever is leaving the bank should come directly after the comma. In that example, the purse is coming after the comma, not Evelyn. Sentence two shouldn't have a comma after stolen, otherwise it would be fine (not including the pronoun issue).
Hope that helps!
