Prepositions

Prepositions may precede a noun or pronoun; or as a sentence-terminal preposition.

1. This is the issue we are concerned with.

2. This is the issue with which we are concerned.

Both of these are grammatically correct despite prescriptive rules saying otherwise. The first example is the most natural and casual way of speaking. However, only the second example should be used when speaking in formal contexts or within formal writing such as academic papers or legal documents. The second one also sounds more poetic or stylistic but many people may feel that it sounds awkward and should never be used.

Many grammarians may argue the first example is grammatically wrong but this is not true. It comes from a shift in the 17th and 18th centuries and the preference of an Oxford professor that saw to making English more like Latin of which terminal prepositions do not exist because word order doesn't allow it.
