A more thorough explanation:

Definition: To transfer something to another person in exchange for money or other valuable item. It can also mean to sell goods by hawking or peddling, or to publicly state or publish something.

Example 1: I vended my old phone to my friend for $50.

Example 2: The street vendor vends fruits and vegetables every morning.

Example 3: The author vended his new book at the book fair.

These examples illustrate how vend means to transfer ownership of something in exchange for money or other valuable item. The first example shows a personal transaction, while the second and third examples show commercial transactions.
