Teazel is a unique word with few synonyms that capture the same meaning. One possible synonym is "card", which is a tool used to comb fibers or materials to make them easier to work with. Another option is "tease", which denotes the action of pulling apart or fluffing something, such as wool or bird feathers. "Bristles" also comes to mind, as it refers to the stiff, spiky hairs found in brushes or certain plant parts that can be used to groom or scrape. Despite these possibilities, none fully capture the essence of "teazel" as a specific type of prickly plant used for textile processing.
