読まなくなった本は古本屋に売りますって英語でなんて言うの？

There are a few different ways to say this. You could say "I sell my old books", and in this context, anyone would know that by "old" you mean that you've already read them. You could also specify "books I don't read anymore." As for the bookstore, you could call it a "second hand bookstore" or a "used bookstore." "Second hand" means that someone else used it first. That is to say, it's not new. "Used" means the same thing - it's just shorter and probably more common. For example, if you don't have enough money for a new car, you'd go to the used car dealership.

It is more common to hear someone refer to a second-hand bookstore as a used bookstore, it often sounds more casual, or natural. Often people give or donate their books to these stores, or they may even sell their books online. So being specific in your explanation is beneficial. The second example gives an explanation of what you do when you are no longer in need of your old, unused book collection. If someone is curious, this tells them what you do with your collection when you no longer desire it.

When you want to explain that you do not keep books that you do not read anymore and that you get rid of them by selling them to secondhand bookstores, then you may explain this in the following ways: -Once I'm done using a book, I sell it to secondhand bookstores. -I don't keep books I don't read anymore. I sell them to secondhand bookstores.

If you want to explain that you sell your second hand books then you could simply say 'I sell books that i dont read/need anymore' If you want to explain what you do with them then you could say 'I sell books to the second hand bookshop that i dont read./need anymore'

Secondhand = Used by someone else first. Your car is second hand if it has had an owner before you Bookstores = American English term for a shop that sells books Book shop = British English term for the same, although bookstore would also be understood Specialise = They concentrate on this item or skill. This is the British English spelling. In American English spell it with a Z - specialize

Even though online books are more and more popular these days, many people still like physical books so it is a good idea to sell off your old books when you have finished with them so that someone else can appreciate them. To describe this practice, say something like "I sell the books that I have finished with to second-hand bookstores."
