icicle

An icicle is a long, narrow piece of ice that forms when dripping water freezes, usually on a roof, branch, or pipe in very cold weather. It often hangs down and comes to a point at the end. You may see it after snow starts to melt during the day and then freezes again when the temperature drops.

Icicles are a familiar sign of winter and often shine in sunlight, which is why they appear so often in holiday scenes and snowy pictures. They can look beautiful, but they can also be dangerous if they break off and fall. In some cases, large ones on a house can be a sign of melting and refreezing around the roof.

An icicle is a hanging piece of ice that forms when water drips from a surface and freezes as the air stays cold. You often see one along the edge of a roof, on a tree branch, on a rock, or under an outdoor pipe or faucet. As more water runs over the same frozen part and freezes again, the piece grows longer. It is usually thicker at the top and thinner at the bottom, ending in a point.

This shape forms little by little. Water may melt from snow or ice during a warmer part of the day, then drip and freeze again when the surface or air is cold enough. Each new layer adds to the length. That is why these hanging pieces are common in winter, especially during weather that shifts between slight melting and freezing.

People often think of icicles as part of a quiet winter scene. They can sparkle in the light and make a place look calm, cold, or festive, so they often appear in stories, pictures, and seasonal decorations. At the same time, they are not just decorative. A large one can fall and hurt someone, and many of them forming along a roof can suggest a problem with heat loss, melting snow, or ice buildup.

So when you hear this word, think of a pointed piece of hanging ice made by freezing drips: something simple in form, strongly tied to winter, and sometimes beautiful, but sometimes a warning sign too.
