Indicating Logical Connections

Three groups of transitional expressions can indicate the logical connection between two ideas.

1. The first group, which includes because, for, and due to, indicates causal relationships: "Idea A because Idea B." For example:

I stopped asking David Mansfield for writing help, because he doesn't fix my spelling or grammar.

2. The second group, including therefore, ergo, and thus, indicates consequences: "Idea A therefore Idea B." For example:

He doesn't even write on my paper; therefore, I don't know what he wants me to do.

(Note: If you are puzzled by the semicolon above, check out the article on Semicolons and Colons.)

3. The third group, including but and however, indicates a contrast or inconsistency: "Idea A but Idea B." For example:

David Mansfield helps me identify errors in my writing, but he doesn't fix my spelling or grammar.

This sentence flows easily from the first idea to the second and clearly indicates the relationship between them.
