What does solvate mean?
To solvate is to form a solvate, a chemical complex in which solvent molecules are directly associated with a central ion or molecule. The verb is used chiefly in chemistry, particularly when describing the coordination of water, ammonia, or other solvent molecules around a metal ion. The noun names the resulting complex. Although both a solvent and a solute may be present in ordinary solutions, a solvate implies a more specific relationship than simple dispersal: some solvent molecules are bound or coordinated to the central species. This distinction is important in coordination chemistry and in discussions of crystal structures, molecular association, and chemical behaviour. The term is technical and relatively uncommon in general prose, but it precisely identifies a state in which a dissolved species has a defined chemical relationship with molecules of its surrounding medium.
To form a chemical complex in which solvent molecules are directly associated with a central ion or molecule.
"The solvent molecules solvate the metal ion."
Used in technical chemistry, especially coordination chemistry.
A complex formed when solvent molecules are directly associated with a central ion or molecule.
"The structure was identified as a stable metal solvate."
Most often encountered in technical descriptions of complexes and crystal structures.
The plural is uncommon because individual solvates are usually discussed in the singular.
"The researchers compared several solvates with different coordinated solvents."
A solvated ion is not merely surrounded by liquid: some solvent molecules are directly bound to it in a distinct chemical arrangement.

Where does solvate come from?
The word was formed within the Latin-derived vocabulary of chemistry from Latin solvere, meaning “to loosen” or “unbind,” combined with the chemical suffix -ate. English solve, solvent, solution, and dissolve belong to the same Latin root. In modern chemical usage, the term distinguishes direct coordination of solvent molecules to a central ion or molecule from the more general process of dissolution.

How solvate is actually used
A specialized term used primarily in chemistry, especially coordination and solution chemistry. It should not be used as a general synonym for dissolution unless the chemical association is relevant.
Easily confused with solvate
A solvent is the liquid or other medium in which a substance dissolves, whereas a solvate is the complex formed through the direct association of solvent molecules with a central ion or molecule.
A solute is the substance being dissolved in a solvent, while a solvate refers to the coordination complex that can result when solvent molecules bind directly to it.
