@zaji970 SCP has different meaning depending on the context.
1. SCP the foundation and its goal (Secure, Contain, Protect)
2. SCP the protocol (Standard Containment Procedure/Protocol)
3. SCP the designation code (SCP - <id> - <sub id>)
It refer to the staff, designation code of the anomaly, the organization, and the goal of the one that "deals" with the anomaly. Basically the beekeeper, the box that keeps the bee, and the entire bee farm
Anomalous object are any object that were deemed by the SCP Foundation as anomalous, not normal, and can be a problem to general society. Basically the bees and their honey
The same goes for phenomenon, it's an anomaly that doesn't have a physical form. Think of it as a Tornado, it's just a really fast wind spinning very fast.
Both doesn't have to be dangerous, but as long there's a risk, the SCP Foundation aren't willing to give it any chance and so they had to "deals" with it and that is their goal (Secure, Contain, Protect) using their necessary procedure/protocol (Standard Containment Procedure/Protocol). And to prevent confusion of their name, they need a way to name them effectively (SCP - <id> - <sub id>)
