Etymology: A crosswind is about as transparent as English compounds get: it is simply a wind that crosses the line of travel. The "cross" half descends from Latin "crux", the cross on which Christ was crucified, which passed into Old English and Old Norse as a word for the cross-shaped object, and "wind" comes from Old English "wind", tracing back to a Proto-Germanic form. Both halves are old native material, so the compound needed no special coinage. The sense of "cross" that matters here is the older one of lying across or at right angles. Once a word for an object shaped like a cross came to mean "across," a wind striking a path at a slant or right angle could be described by joining the two. The compound is the kind of plain descriptive formation that English produces readily whenever a new direction or relationship needs naming.

Synonyms: sidewind, lateral wind, cross-breeze
