An adhesive substance that holds things together is called glue.
When we think about glue, we often think about putting it on something and watching as two separate pieces stick together. We use it to repair broken toys or attach a photo to a wall. You can find glue in a bottle at most hardware stores or supermarkets, usually in the craft aisle. It comes in different types, like white glue for paper and clear glue for plastic. Some people also talk about "glue" as a verb, meaning to stick two things together using an adhesive - for example, "Can you glue this picture frame onto the wall?"
A hard gelatin made by boiling bones and hides, used in solution as an adhesive; or any sticky adhesive substance.
Example: Near-synonyms: adhesive, cement
