Signs

Signs are observable indicators or clues that point to a particular condition, problem, or situation. They are objective evidence—such as symptoms visible to others or measurable data—that help healthcare professionals diagnose or assess health issues. For example, a fever, rash, or high blood pressure are signs that can signal an underlying illness. In a broader context, signs can also refer to signals or symbols that communicate messages or instructions, like traffic signs. Overall, signs serve as important cues that provide information to help understand or evaluate a situation accurately.
