A more thorough explanation:

A nontransferable ticket is a type of ticket that cannot be transferred from the person who purchased it to another person. This means that the person who bought the ticket is the only one who can use it.

For example, if you buy a nontransferable airline ticket, you cannot give it to someone else to use. The ticket is only valid for the person whose name is on it.

Most airlines have a strict no-name change policy, which means that you cannot change the name on the ticket to someone else's name. This is why most airline tickets are non-transferable.

Another example of a nontransferable ticket is a concert ticket. If you buy a nontransferable concert ticket, you cannot sell it or give it to someone else to use. The ticket is only valid for the person whose name is on it.

These examples illustrate the definition of a nontransferable ticket because they show that the ticket cannot be transferred to another person. The ticket is only valid for the person whose name is on it, and it cannot be used by anyone else.
