/ʌnəˈsɜrtənd θɪŋ/ – Phrase
Definition: sự vật không xác minh được.
A more thorough explanation: An unascertained thing refers to an item or object that is not specifically identified or determined at a particular point in time. In legal terms, it may refer to a generic or unspecified item that is part of a larger group or category, making it difficult to pinpoint or ascertain its exact nature or characteristics.
Example: The contract stated that the seller would be responsible for any loss or damage to unascertained things during transportation.
