What is the term for deliberately giving false or misleading information under oath?

The term for deliberately giving false or misleading information under oath is perjury. This legal concept involves a breach of the oath that witnesses take to tell the truth during legal proceedings. When an individual swears to tell the truth and then intentionally provides false statements, they commit perjury. This offense is taken very seriously in the legal system because it undermines the integrity of the judicial process, as truthful testimony is crucial for achieving justice.

The other terms provided do not relate to this legal action. Perturbation refers to a state of anxiety or mental uneasiness; Philistine denotes someone who is indifferent to culture and the arts; and profundity implies a deep insight or understanding. None of these definitions aligns with the act of lying under oath, which solidifies why perjury is the appropriate term.
