Words sorting logic in Bubble Word Jam Level 644
In this puzzle, each word must be placed into a category that shares a common theme. Some categories also have nested subcategories, meaning a smaller group of words fits under a broader heading. Understanding these relationships helps you see why certain words belong together.
TEXTILE MATERIALS
The main idea of TEXTILE MATERIALS is natural fibers used to make fabric. All members are plant‑ or animal‑based materials spun into thread.
- COTTON belongs here because it is a soft, fluffy fiber from the cotton plant, widely used for clothing.
- LINEN is made from flax plant fibers and is valued for its coolness and strength.
- SILK is produced by silkworms and is known for its smooth, luxurious texture.
Under TEXTILE MATERIALS there is also a subcategory WOOL. Unlike the direct words, WOOL represents a group of specific wool types, each from different animals.
- ANGORA comes from the Angora rabbit and is extremely soft.
- CASHMERE is a fine, warm fiber from Cashmere goats.
- MERINO is a high‑quality wool from Merino sheep, known for its softness.
- MOHAIR is produced from Angora goats and has a silky, lustrous sheen.
