glutinous

The word glutinous describes something sticky, glue-like, or gummy. It comes from the Latin word gluten, which originally meant "glue." Because of that history, the word is closely tied to the idea of something that clings, stretches, or feels thick. Even though it looks similar to the modern word "gluten," glutinous usually refers to texture, not to the protein found in wheat and some other grains.

This is why "glutinous rice" can confuse learners at first. The name refers to the rice's sticky, chewy texture after cooking, not to the presence of gluten. In everyday use, glutinous is most often used for foods such as sticky rice, mochi, thick porridge, paste-like fillings, syrups, and sauces that feel heavy and adhesive. It can also describe non-food substances like glue, gum, mud, or any thick material that sticks to surfaces.

In a broader and more figurative sense, glutinous can describe something that seems to cling or hold on in an unpleasant way. A process, argument, or situation might be called glutinous if it feels sticky, slow, and hard to get free from. That figurative use exists, but it is less common than the physical one.

So when you see glutinous, the safest meaning is usually simple: something thick and sticky, often with the soft, chewy, adhesive quality of sticky rice or paste.
