What does a */* mean in a sentence [closed]

What does a / mean in a sentence, for example, "They read/reviewed the books they have." I can't find an answer to this question, but they only get an opinion which is what I do not need.

Solution 1:

To be very clear, my understanding is that a / (slash) is just an easy way or symbol of saying "and or or" (an example I could've used there is and/or!)

In your example, the sentence is just meaning:

They read and/or reviewed the books they have.

If you want to find a clearer definition, you could also call the "/" character a virgule. There are many other names, but these are the most popular.
