**Presumably** is an adverb that expresses a reasonable assumption or likelihood based on available information. Here are some examples of its usage:
1. **Presumably**, the train will arrive on time, as it is rarely delayed.
2. She claimed to have lost her phone, but **presumably**, she just forgot where she put it.
3. **Presumably**, they will send us the contract by tomorrow, as they promised to do so.
4. He said he had a lot of work to do, but **presumably**, he exaggerated, as he usually doesn't work that much.
5. **Presumably**, the weather will be nice tomorrow, as it has been sunny all week.
6. **Presumably**, they will agree to our terms, as they seem like reasonable people.
7. **Presumably**, he won't come to the party, as he hates social events.
8. **Presumably**, she will be able to finish the project on time, as she is a hardworking person.
9. **Presumably**, they won't be able to attend the meeting, as they are on vacation.
10. **Presumably**, they will enjoy the movie, as they like similar genres.
In each of these examples, «presumably» is used to express an assumption based on what is known or expected, acknowledging that there is no guarantee of accuracy.
