Morphology

chloral + hydrate

The term denotes the hydrate (water-bound) form of the chemical chloral, so a learner who knows 'chloral' is a sedative chemical and 'hydrate' is a crystalline substance with bound water can infer it is a crystalline sedative compound. This noun+noun chemical naming pattern is compositional and follows predictable morphological logic, making the meaning derivable from the constituents.

Etymology

Chloral hydrate gets its name from chemistry: it is the water ('hydrate') form of a chemical that contains chlorine called 'chloral'. These clear crystals were used as a drug to help people 'sleep', so the name points directly to the substance now used as a sedative.
