Core difference
Oxford directly documents famous as something and famous for something and gives examples that show the role-versus-reason distinction.
Style Boundary
The two patterns can coexist for the same subject, but they answer different questions: in what capacity versus for what reason.
Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
Agree With vs. Agree On separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Angry With vs. Angry About separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Appropriate For vs. Appropriate To separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Available To vs. Available For separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Be Bound To Do vs. Bound For Somewhere separates two distinct Oxford-documented senses. Bound to do/be expresses certainty or likelihood, while bound for + destination describes travel toward a place. The guide keeps those senses separate from legal or duty-bound uses.
Be Elated To Do vs. Elated By Something compares two directly documented complement patterns for “elated.” Oxford evidence supports an infinitival use as well as elated at/by + noun phrase, so the guide explains the construction choice without generalizing from synonyms.
