Reason & purpose
because (of), due to, so that, in order to.
The rules
- "Because of" + noun; "because" + clause ("because it was foggy").
- Purpose + verb: "in order to catch" (or simply "to catch").
- Purpose + full clause: "so that nobody would hear".
- Purpose = "to" + verb. "For + -ing" describes function, not purpose of a trip.
- "Due to" + noun, formal twin of "because of".
- Purpose infinitive at the end: "…to save money".
- "Owing to / due to" are formal; "'cause" is spoken slang.
