Does the word used on Amazon, means second hand

Yes, on Amazon, the term "used" typically refers to items that have been previously owned or used by someone else. These items may show signs of wear and tear but are generally still functional. Sellers can list items as "used" to indicate that they are not brand new. Amazon often provides details about the condition of the used item, which can vary from "like new" to "acceptable." Always check the item's description for specifics on its condition before purchasing.
