Testimony is a solemn attestation as to the truth of a matter.
Etymology
The words "testimony" and "testify" both derive from the
Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ...
word ''testis'', referring to the notion of a disinterested
third-party witness.
Law

law, testimony is a form of
evidence
Evidence for a proposition is what supports the proposition. It is usually understood as an indication that the proposition is truth, true. The exact definition and role of evidence vary across different fields. In epistemology, evidence is what J ...
in which a
witness
In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.
A witness might be compelled to provide testimony in court, before a grand jur ...
makes a "solemn declaration or affirmation ... for the purpose of establishing or proving some fact". According to
Bryan A. Garner, the editor of ''
Black's Law Dictionary'', the word "testimony" is properly used as a
mass noun (that is, always uninflected regardless of

A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can ...

count noun.
Testimony may be oral or written, and it is usually made by
oath
Traditionally, an oath (from Old English, Anglo-Saxon ', also a plight) is a utterance, statement of fact or a promise taken by a Sacred, sacrality as a sign of Truth, verity. A common legal substitute for those who object to making sacred oaths ...
or
affirmation under penalty of
perjury. Historically, to be admissible in court and to ensure maximum reliability and validity, written testimony presented in the form of an
affidavit (i.e., the witness would not be appearing in court at the hearing at which the affidavit was considered as evidence) was usually witnessed by another person (in many common law jurisdictions, a
notary public) who had to also swear to or affirm its authenticity, also under penalty of perjury. In 1976, the
United States Congress

enacted a statute allowing for the use of an unsworn declaration under penalty of perjury in lieu of an affidavit in
federal courts.
In other words, the declarant's signature together with a statement that they were making the unsworn declaration under penalty of perjury were deemed as a matter of law to be sufficiently solemn to remind the declarant of their duty to speak the truth, the whole truth, and nothing but the truth (meaning notarization was no longer required).
As of 2006, about 20 states also had similar statutes allowing the use of unsworn declarations in their
state courts.
Unless a witness is testifying as an
expert witness
An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as ...
, testimony in the form of opinions or inferences is generally limited to those opinions or inferences that are rationally based on the perceptions of the witness and are helpful to a clear understanding of the witness' testimony.
Legitimate expert witnesses with a genuine understanding of legal process and the inherent dangers of false or misleading testimony refrain from making statements of fact. They also recognize that they are in fact not witnesses to an alleged crime or other event in any way, shape or form. Their expertise is in the examination of evidence or relevant facts in the case. They should make no firm judgement or claim or accusation about any aspect of the case outside their narrow range of expertise. They also should not allege any fact they can not immediately and credibly prove scientifically.
For example, a hair sample from a crime scene entered as evidence by the prosecution should be described by an expert witness as "consistent with" a sample collected from the defendant, rather than being described as a "match". A wide range of factors make it physically impossible to prove for certain that two hair or tissue samples came from a common source.
Having not actually witnessed the defendant at the scene, the expert witness can not state for a fact that the sample is a match to the defendant, particularly when the samples were collected at different times and different places by different collectors using different collection methods. Ultimately, the testimony of expert witnesses is regarded as supportive of evidence rather than evidence in and of itself, and a good defense attorney will point out that the expert witness is not in fact a witness to anything, but rather an observer.
When a witness is asked a question, the opposing attorney can raise an
objection, which is a legal move to disallow or prevent an improper question to others, preferably before the witness answers, and mentioning one of the standard reasons, including:
* argumentative
* asked and answered
*
best evidence rule
* calls for speculation
* calls for a conclusion
*
compound question or narrative
*
hearsay
* inflammatory
* incompetent witness (e.g., child, mental or physical impairment, intoxicated)
* irrelevant, immaterial (the words "irrelevant" and "immaterial" have the same meaning under the Federal Rules of Evidence. Historically, irrelevant evidence referred to evidence that has no probative value, i.e., does not tend to prove any fact. Immaterial refers to evidence that is probative, but not as to any fact material to the case. See Black's Law Dictionary, 7th Ed.).
* lack of
foundation
*
leading question
*
privilege
* vague
*
ultimate issue testimony
There may also be an objection to the answer, including:
* non-responsive

, an attorney often had to follow an objection with an exception to preserve the issue for appeal. If an attorney failed to "take an exception" immediately after the court's ruling on the objection, he waived his client's right to appeal the issue. Exceptions have since been abolished, due to the widespread recognition that forcing lawyers to take them was a waste of time.
When a party uses the testimony of a witness to show proof, the opposing party often attempts to
impeach the witness. This may be done using
cross-examination, calling into question the witness's
competence, or by attacking the
character or
habit of the witness. So, for example, if a witness testifies that he remembers seeing a person at 2:00 pm on a Tuesday and his habit is to be at his desk job on Tuesday, then the opposing party would try to impeach his testimony related to that event.
Government
Testimony is given by those invited or compelled to speak at, or submit a written statement to, legislative hearings such as
United States congressional hearings.
Testimony may also be given to a regulatory agency as part of the process of making or changing
regulations.

An individual who no longer believes in the religion may be referred to as having "lost their testimony".

, testimony is a proposition conveyed by one entity (person or group) to another entity, whether through speech or writing or through facial expression, that is based on the entity's knowledge base. The proposition believed on the basis of a testimony is justified if conditions are met which assess, among other things, the speaker's reliability (whether her testimony is true often) and the hearer's possession of positive reasons (for instance, that the speaker is unbiased).
We can also rationally accept a claim on the basis of another person's testimony unless at least one of the following is found to be true:
# The claim is implausible;
# The person or the source in which the
claim is quoted lacks
