namely
Specifically; used before giving exact names or details.
Namely means “specifically” or “that is to say.” You use it when you want to identify exactly who or what you're talking about.
If someone says “Three planets have rings, namely Saturn, Jupiter, and Uranus,” they're telling you precisely which planets they mean. The word signals that a specific list or explanation is coming next.
You might write, “My favorite subjects are sciences, namely biology and chemistry,” to clarify exactly which sciences you prefer. Or a teacher might say, “One student volunteered to help, namely Marcus,” to identify who stepped up.
The word works like a spotlight, pointing directly at the specific examples or names that matter. It's particularly useful in writing when you want to be clear and avoid confusion. Instead of leaving readers wondering “which ones?” or “who exactly?” namely introduces the precise answer. Think of it as saying, “I'm about to tell you the exact names or details.”
