N2
~ことから
from the fact that; hence the name
When to use it
Use ~ことから when you want to present an observed fact as the grounds for a conclusion, judgment, decision, or a name. It is heavier and more analytical than ~から/~ので, so it fits reports, minutes, proposals and email where you show your reasoning rather than just state a cause. It cannot introduce a request, invitation or command in the main clause — the second half must be a conclusion, assessment, or resulting action.
