The word Harbinger is one that I previously associated with bad occurrences. But when I went to verify the definition(s), I found it actually is neither bad nor good:
1. one that pioneers in or initiates a major change
2. one that presages or foreshadows what is to come
As you can see, it depends what the person/event is a harbinger of. The common saying is a harbinger of doom, but you could just as likely be a harbinger of success.
This is just one of those words I like. I like the way it sounds when I say it. It even sounds ominous, which it very well could be.
I am the harbinger of more fun words (okay, it doesn't have quite the same impact as harbinger of doom).
What are you a harbinger of?
