testify

B2
verb

Pronunciation

UK

  • /tˈɛstɪfˌaɪ/

US

  • /ˈtɛstəˌfaɪ/

Description

To testify means to give a formal statement as evidence, often in court, but it does not always happen in a courtroom. You can also testify to someone's character, meaning you speak about what kind of person they are. Think of it like this: if your friend is blamed for something they did not do, you might speak on their behalf, sharing what you know about them and defending their good name.

The word comes from the Old French "testifier," meaning "to bear witness." A witness testifies by sharing what they saw or heard. You might read in history books that someone testified before Congress, giving their view on an important issue. Or you could say, "Her actions testify to her courage," meaning her bravery is clear in what she does.
