Unnecessary words

Here's a classic case: "The reason why I did it was..." You don't need the "why." Another case using the same type of statement: "The reason for this is because..." Again, stick to reason, drop "because." It's redundant. You can substitute "that" for many examples. "The reason for this is that I..." If you like "why" or "because" (and what's not to like?), there are obviously ways of inserting them properly. Happy writing, everyone.
