The word "wool fat" has an interesting etymology. It comes from combining two separate words, "wool" and "fat".
- "Wool" originates from the Old English word "wull", which later evolved into "wolle" in Middle English. It is related to similar words in other Germanic languages, such as the Old Norse "vǫlr" and Old High German "wolla".
- "Fat" comes from the Old English word "fǣtt" or "fǣt", which means "fatted" or "fatty". It can be traced back to the Proto-Germanic word "faitida", related to the Gothic "faitheis" and Old High German "feiz".
When these two words are combined, "wool fat" refers to fat extracted from the wool of sheep. Wool fat is also commonly known as "lanolin".
