- Incidentally: This suggests that something is mentioned as a minor or additional point.
- Unintentionally: Similar to “accidentally,” but may not necessarily involve a negative outcome.
- Fortuitously: This means something happened by good luck or fortunate coincidence.
- As luck would have it: This emphasizes the role of luck in a positive or surprising event.
- Coincidentally: This highlights that two or more things happened at the same time or place by chance.
