1
give evidence in a legal setting
To speak in court and say what you know about a crime or legal problem, usually after promising to tell the truth.
用法パターン：
to testify in [court] / to testify about [something]
よくある間違い：
Learners sometimes confuse "testify" with "test" and say things like *"He will test in court"* instead of *"He will testify in court"*. Another common mistake is using a direct object incorrectly, e.g. *"He testified the crime"*. Instead, say *"He testified about the crime"* or *"He testified that he saw the crime"*.
類義語
give evidence (Common legal phrase; slightly more general and less formal-sounding than testify, can include written or spoken statements.)
対義語
remain silent (Describes choosing not to speak or give information, especially when you have the right not to testify.)

2
state as true from experience
To say in a strong way that something is true because you know it from your own life or experience.
用法パターン：
to testify to [something] / to testify that [clause]
よくある間違い：
Learners sometimes use "testify" where a simpler verb like "say" or "tell" is more natural in everyday speech. For example, *"He testified that the movie was good"* sounds overly strong or formal; in casual talk, "He said the movie was good" is better. Also, the preposition is often wrong: it is usually *"testify to something"* (not *"testify about something"*) in this general, non-legal sense.
類義語
attest (More formal; often used in written English and official contexts when confirming that something is true or correct.)
対義語
deny (Means to say that something is not true, which is the opposite of testifying that it is true.)

speak publicly about faith
To speak in front of other people, often in a church, and tell them what you believe and what you think God has done for you.
用法パターン：
to testify about [one's faith] / to testify to [God's goodness]
よくある間違い：
Learners may not realize this meaning is mainly used in Christian or similar religious contexts. Using it about general opinions (e.g. *"He testified about his love for football"*) sounds strange; in such cases, verbs like "talk" or "speak" are better.
類義語
witness (In Christian contexts, "witness" as a verb has a very similar meaning, but can also include living in a way that shows one’s faith, not just speaking.)
対義語
hide your faith (Describes choosing not to speak openly about your religious beliefs, which contrasts with publicly testifying about them.)

|testify about God's goodness

serve as evidence or proof
When facts or things show very clearly that something is true.
用法パターン：
[something] testifies to [something]
よくある間違い：
Learners sometimes try to use this sense with a person as the subject in very casual contexts, where simple verbs like "show" or "prove" are more natural. Also, they may forget the preposition "to" and say *"The results testify the success"* instead of *"The results testify to the success"*.
類義語
demonstrate (Very close in meaning but more common; often used for evidence clearly showing that something is true.)
対義語
contradict (If evidence contradicts a claim, it shows the claim is not true, which is the opposite of testifying to it.)
