# And vs. Or

Both **and** and **or** are coordinating conjunctions used to join grammatically equal elements, but each of them indicates a different relationship between these elements.

Use **and** to show that all listed elements are true at the same time. In terms of logic, the statement *a = b and c* means that:

- If both *b* and *c* are true, then *a* is true.
- If either *b* or *c* is false, then *a* is false.
- If neither *b* nor *c* is true, then *a* is false.

Use **or** to show that only one element can be true at one time. In terms of logic, the statement *a = b or c* means that:

- If either *b* or *c* is true, then *a* is true.
- If both *b* and *c* are true, then *a* is false.
- If neither *b* nor *c* is true, then *a* is false.

In negative sentences, use **or** unless the listed elements are part of the same logical unit. For example, *restore of files and folders*.

::: important

DO NOT use **and/or** — this conjunction means that either all listed elements or only one of them is true at the same time. To avoid using **and/or**, you can do either of the following:

- Use either **and** or **or** according to the described logic — in most cases, **and/or** can be replaced with **and**.
- Rephrase the whole sentence or introduce a verb to list all possible options.
