Hand signs are gestures made with the hands to convey messages or emotions without using words. They can be used in various contexts, such as communication between individuals who are deaf or hard of hearing, where sign language, like American Sign Language, is employed. Hand signs can also serve as non-verbal cues in everyday interactions, helping to express feelings or emphasize points. In addition to sign language, hand signs can include symbols or signals used in specific activities, such as sports or military operations. These signs often have agreed-upon meanings that facilitate quick and clear communication among participants, enhancing teamwork and understanding in various situations.
