Word story

Weather and its (Germanic) kindred terms wind and window are derivatives of the very common, very complicated Proto-Indo-European root awe-, awē-, wē- “to blow.” The variant awe- is the source of Germanic wedram “storm, weather” (Old English weder, English weather ). The suffixed variant wēn- forms Latin ventum “wind,” and English wind and window.
Window is first recorded in Middle English in the first half of the 13th century. It comes from Old Norse vindauga “wind eye,” originally an opening in a gable or roof to release smoke and admit light. (The Old Norse word came into Old English before the initial w- became v- in literary Old Norse.)

Science definitions for weathering (1 of 2)

weathering

[ wĕðər-ĭng ]

Any of the chemical or mechanical processes by which rocks exposed to the weather undergo chemical decomposition and physical disintegration. Although weathering usually occurs at the Earth's surface, it can also occur at significant depths, for example through the percolation of groundwater through fractures in bedrock. It usually results in changes in the color, texture, composition, or hardness of the affected rocks.

The state of the atmosphere at a particular time and place. Weather is described in terms of variable conditions such as temperature, humidity, wind velocity, precipitation, and barometric pressure. Weather on Earth occurs primarily in the troposphere, or lower atmosphere, and is driven by energy from the Sun and the rotation of the Earth. The average weather conditions of a region over time are used to define a region's climate.
