⚡ Since or Because Quick Answer
Use because to show a clear reason.
Use since to show either time or a reason—but it is best for time in formal writing.
✅ Examples:
- Reason: “I stayed home because it was raining.”
- Time: “I’ve lived here since 2010.”
- Possible but sometimes unclear: “I stayed home since it was raining.” (Reason, but can sound like time)
👉 Best rule:
Use because for reasons.
Use since for time.
📜 The Origin of “Since” and “Because”
- Since comes from Old English sithen, meaning “after that time.”
- Because comes from Middle English bi cause, meaning “by cause” or “for the reason that.”
Originally, since only meant time, but over centuries it also gained a second meaning: reason.
Because has always been the clearer choice for showing cause.
👉 That’s why confusion exists today—since has two roles, and because has one strong role.
