"disused" is the most accurate word for describing an item that is no longer used but has been used in the past.
If you refer to an item as being "unused" it can be interpreted in 2 ways:
1. an item that is no longer used
2. an item that has never been used
therefore it can be unclear to say that you have an "unused desk" as it could mean either which have very different meanings.
If an item is "second-hand" it means that the item has had a previous owner. This sentence implies that the previous owner no longer uses it.
"disused"は過去には使われていたがもはや使われなくなったものを示す最も正確な単語です。
もしあなたが何かを"unused" として表現した場合、２つの方法で訳されるでしょう。
1. もはや使われていないもの
2. 一度も使われていないもの
したがって、あなたが"unused desk"を持っているということはとても異なる意味を表すことができるので、とても不明確な言い方になるでしょう。
もし何かが"second-hand"であれば、 it means that the item has had a previous owner. This sentence implies that the previous owner no longer uses it.
My mom have a lot of unused furniture in her office.
My dad gave me his old car.
I am selling some second-hand items.
▪ My mom have a lot of unused furniture in her office.
unused = furniture that are not being used.
This means that your mom has stuff in her office that is just standing around and not being used.
▪ My dad gave me his old car.
Old car = used car that he is not using anymore.
▪ I am selling some second-hand items.
second-hand items is items that is not new anymore more. It is items that has been used and is no long needed and that's why you are selling them.
▪ My mom have a lot of unused furniture in her office.
unused
= 使われていない家具のこと。
これは、あなたのお母さんの職場に、ただそこにあるだけで使われていないものがあるということを意味しています。
▪ My dad gave me his old car.
Old car
= もう使われていない中古の車のこと。
▪ I am selling some second-hand items.
second-hand itemsとは、もう新しくないもののこと。
それは使われていたもので、今はもう必要とされておらず、そのため売ろうとしているもののことを意味しています。
If you used an item before but you do not use it anymore for any reason, the item is unwanted or not in use anymore. You can also say that the item is unused. An unused item would also mean an item that was
given to you, but has never been used by you. If you do not use an item because it is old-fashioned or out out of date, then you can call the item 'obsolete' For example: the typewriter became obsolete with the invention of the computer. This desk is not used by us anymore.
もしあなたが何かを以前は使っていたがなんらかの理由があり使わなくなったのであれば、それは今は必要なく、もはや使われていないということになります。
また、それはunusedであるということもできます。
. An unused item はまた、あなたがもらったもので、一度も使われなかったもののことも意味します。
もしあなたがそれを古臭かったり、時代遅れだから使わないのであれば、それを'obsolete'と呼ぶこともできます。
例：
the typewriter became obsolete with the invention of the computer.
This desk is not used by us anymore.

We can use the first example as the most general by saying that it's something that we "don't use anymore." We can also say that an item is, "second-hand," meaning that someone gave it to us or donated it to us. We can use the expression, "see much use anymore," as a way to say that the item isn't used anymore but at one point it was used a lot more.
