This one always gets me. How do I introduce an idea and then state it in the same sentence? Does it simply require a colon?
That’s because we have one goal: for you to consider your website a
There are numerous different ways to express ideas in a single sentence. Your use of a colon is perfectly fine, but here are a few other examples:
- That is because the one goal we have is for you to consider your website a success.
- That is because we only have one goal, which is for you to consider your website a success.
- That is because we have one goal—for you to consider your website a success.
You can see that there are multiple ways to say what you’re looking for, but in my opinion a colon works best if you want to emphasize the latter part of your sentence. It is the most clear one of these sentences, along with perhaps the sentence containing a dash. The other sentences seem to put less emphasis on what the goal is.
