Originally, an **alcoholate** was the crystalline form of a [salt](/source/Salt_(chemistry)) in which [alcohol](/source/Alcohol_(chemistry)) took the place of [water of crystallization](/source/Water_of_crystallization), such as [SnCl3(OC2H5)·C2H5OH]2[1] and [C8H6N4O5](/source/Nitrofurantoin)·CH3OH.[2] However this denomination should not be used anymore for the ending -ate often occurs in names for anions.[3]

The second meaning of the word is that of a [tincture](/source/Tincture), or alcoholic extract of plant material.

The third, and more usual meaning of the word is as a synonym for [alkoxide](/source/Alkoxide)— which is the conjugate base of an alcohol.
