Wave

Return to > Dictionary

1. Definition + Rich Everyday Explanation

Wave (noun / verb) ( veyv) = a moving ridge of water on the sea; a gesture made by moving the hand side to side; a sudden increase or surge of something; OR to move the hand in greeting or signal, or to move gently back and forth.

This word captures movement that rises, spreads, and passes — whether that’s water moving across the ocean, a hand moving through the air, or a phenomenon spreading through a population.

MEANING 1: Water Movement

The most literal meaning is the ridges of water that move across oceans, lakes, and seas. Waves crash on beaches, rock boats, and attract surfers. Small ripples are gentle waves; massive tsunamis are devastating waves. The image of water rising, moving forward, and breaking is the foundation for all other meanings.

MEANING 2: Hand Gesture

To wave is to move your hand from side to side as a greeting, farewell, or signal. You wave hello, wave goodbye, wave to get someone’s attention. It’s one of the most universal human gestures. A wave can be enthusiastic (big, excited movements) or casual (a small lift of the hand).

MEANING 3: Surge or Sudden Increase

Figuratively, a wave describes a sudden increase or spread of something — often emotions, events, or phenomena. A wave of nausea washes over you. A wave of protests sweeps across a country. A heat wave brings unusually hot weather. A crime wave means a sudden increase in criminal activity. Like ocean waves, these surges arrive, peak, and eventually subside.

MEANING 4: Successive Groups

Wave also describes groups that arrive in succession. Immigration comes in waves. Soldiers attack in waves. Guests arrive in waves. Each group is like a wave — arriving, passing, then followed by another.

In physics, waves describe how energy travels — sound waves, light waves, radio waves. This scientific meaning connects to the core image of something spreading outward from a source.

Examples from the street:

• “The waves were too big for swimming” → the sea water ridges were too powerful for safe bathing
• “She waved goodbye from the train” → she moved her hand in farewell from the railway carriage
• “A wave of panic spread through the crowd” → a surge of fear passed rapidly through the gathering
