What do you mean by liquid?

A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. ... When a liquid is cooled, the atoms or molecules lose kinetic energy. If the temperature becomes low enough, the liquid becomes a solid. Water is a good example.

It's a state of matter where particles can move  about and slide past each other.  They are still close together, but not  in a lattice. The forces that hold them  together are weaker than in a solid.
