Why should one avoid using slang during testimony?

Avoiding slang during testimony is crucial because it may hinder the clarity of the statement. Language that is informal or specialized can be ambiguous, as slang often has different meanings based on context or regional usage. Using clear, formal language ensures that the message is communicated effectively and is easily understood by all parties involved, including jurors, lawyers, and judges. Clarity is paramount in legal settings, as any misunderstandings could impact the outcome of a case. Therefore, maintaining a formal tone helps to eliminate potential confusion and allows for a more straightforward presentation of facts.
