secondhand

Secondhand is an adjective used to describe something that did not originate with the person or source being discussed, but rather came from a different source or was previously used by someone else. The term is used in various domains and is usually written as secondhand or second-hand in hyphenated form depending on style guides.

In consumer markets, secondhand goods are items that have been previously owned and are resold. Common categories include clothing, electronics, books, furniture, and vehicles. Buying secondhand offers cost savings and can reduce waste, but it may involve higher risk of wear, missing parts, or limited or no warranty. Transactions occur through thrift shops, consignment stores, garage sales, and online marketplaces, with pre-owned or refurbished labels used to indicate condition.

Secondhand smoke refers to tobacco smoke that enters the surrounding air from a smoker or from burning tobacco products. It is associated with health risks for non-smokers, including heart and lung disease. Many countries and jurisdictions regulate or restrict smoking in public spaces to limit exposure.

Secondhand information refers to data, claims, or reports that are received from others rather than observed directly. Such information may be incomplete or distorted and often requires verification from primary sources. It is a common concern in journalism, research, and everyday communication, where source credibility and bias must be considered.

Other uses include phrases like secondhand experience or secondhand knowledge to describe insights gained through another person. The term emphasizes that the information or object is not original to the holder.
