The word "Span-roof" is a compound word derived from two words: "span" and "roof".
The etymology of "span" can be traced back to the Old English word "spannan" which means "to stretch". It is related to the Old Norse word "spann" which means "shoe last", and the Middle Dutch word "spanne" which means "to measure", indicating the concept of extension or measurement.
The word "roof" also has Old English origins, derived from the word "hrof". It is related to the Old Norse word "hróf" and the German word "Dach". The common Proto-Germanic root word "hrōfą" suggests the concept of "covering" or "overhead protection".
Combining these two words gives us "span-roof", indicating a roof structure that spans or stretches between two points or supports.
