What does glue mean?
Glue is a sticky adhesive used to join materials such as paper, wood, fabric, and plastic. In everyday use, it is usually uncountable and refers to the substance itself: a bottle, tube, or layer of glue. The related verb means to attach something using glue, but it also has a figurative meaning of connecting people, ideas, or groups through a close relationship. Expressions such as “glued to the screen” and “the glue holding a team together” are informal but widely understood. Glue has long been practical and familiar, from craft projects and schoolwork to furniture repair and industrial manufacturing. Its history also reflects human ingenuity: early adhesives were made from animal materials, while modern products may use synthetic or natural ingredients. The word is especially useful because it captures both a literal act of fastening and the metaphorical idea of forming strong bonds.
A viscous adhesive substance used to join materials together; by extension, something that holds people or things together.
"The label had come loose, so he covered the back with glue."
Usually uncountable in ordinary usage. The figurative sense is common in informal and semi-formal contexts.
To attach or fasten something with glue, or figuratively to keep people or things closely connected.
"The two parts of the model were glued together overnight."
The figurative use often suggests a strong attachment, close relationship, or intense concentration and is frequently informal.
Usually uncountable in everyday use; the plural refers to different types or separate supplies of adhesive.
"Several glues are available for different materials."
Glue is one of humanity’s oldest technologies: animal hides and bones were boiled to make hide glue long before modern synthetic adhesives.
