比较义项：挥动手臂或手向人示意（动词）。

• wave

  Wave is a friendly hand gesture for greeting or saying goodbye; it does not ask the other person to move, and often pairs with words like 'goodbye', 'hello', or 'at'.

  wave（挥手）是用来打招呼或道别的友好手势，并不要求对方靠近，常与“goodbye”“hello”或“at”搭配使用。

  She waved goodbye from the doorway and closed the door behind her.

  她在门口挥手道别，然后关上了门。

• beckon 本词

  Beckon means to gesture, often with a curled finger or a hand motion, instructing someone to come closer; it always implies an invitation to approach, unlike a simple greeting.

  beckon（招手示意）指用弯曲手指或手部动作，示意让对方靠近，总带有邀请对方过来的意思，不同于单纯的打招呼。

  The guard beckoned him forward with a curl of his finger.

  警卫弯了弯手指，示意他走近些。

Wave and beckon are hand gestures. Wave is casual, for greeting or saying goodbye, without asking the person to move. Beckon is more formal, often a curled finger, asking someone to come closer. Not compared: beckon as 'seem attractive', or wave as 'ocean wave'.

这两个词都指用手做出的示意动作，但语气和场合不同：wave较随意，多用于打招呼、道别或引起注意；beckon更正式，强调用手势“召唤”对方靠近，意图更明确。这里不比较beckon作“显得诱人、吸引人”的引申义（如原例句中海滩“召唤”着人们），也不比较wave表示“波浪”或“挥动旗帜、物品”等其他用法。
