To make someone believe, or feel sure about something, especially by using logic, argument or evidence.
"The lawyer presented undeniable evidence to convince the jury of her client's innocence."
In plain English: To convince someone means to make them believe something is true by giving good reasons or proof.
"She tried to convince her friends that they should visit the new park on Saturday."
Usage: Use convince to describe the process of persuading someone through arguments or evidence until they accept an idea as true. Unlike persuade, which focuses on inducing action, this word specifically targets changing a person's belief or certainty.
Convince comes from the Latin word convincō, which originally meant "to refute" or "prove." The term entered English as a doublet of convict and replaced an older Germanic phrase that had a similar meaning.
