"Give high sign" is an idiomatic expression used to convey approval, agreement, or understanding without verbal communication. It is typically achieved by using hand gestures, non-verbal cues, or specific movements to signal agreement or to indicate support for someone or something.
The phrase "give high sign" originated from the American slang of the early 20th century. The term "high" is believed to come from the idea that extending one's hand or arm upward signifies a positive or enthusiastic response. It suggests a physical action that is elevated, as if reaching towards the sky or pointing upward. "Sign" refers to a gesture or action that serves as a signal or indicator.
The act of giving a high sign can be as simple as nodding one's head, flashing a thumbs-up gesture, or making eye contact and smiling with enthusiasm. It can also involve more elaborate movements such as raising one's hand and waving it in a specific way, or making a distinctive motion with the fingers.
The purpose of a high sign is to convey non-verbal approval or support quickly and discreetly. It is often used in situations where noise or silence is a factor, such as during a performance or in a crowded environment. The action can serve as a prompt to someone, letting them know they are doing well or that their actions are understood and appreciated.
Overall, "give high sign" refers to the act of using non-verbal cues or hand gestures to communicate approval, agreement, or understanding in a manner that is clear and noticeable to the intended recipient.
