RareTechnical / Scientific
Definition
Meaning
A salt or ester of tannic acid, formed by the combination of tannic acid with a base (e.g., a metal ion or an amine).
In medicine and chemistry, a compound in which tannic acid acts as the acidic component, often used to make certain drugs (like alkaloids) less soluble, more stable, or less irritating for medicinal use. The term is also used in dyeing and leather processing contexts.

Frequently Asked Questions
No, it is a rare, highly technical term used almost exclusively in chemistry, pharmacy, and related scientific fields.
'Tannin' (or tannic acid) is the parent acidic compound found in plants. A 'tannate' is a specific chemical derivative where tannic acid has reacted with a base to form a salt or ester.
It is typically only found in comprehensive or specialised scientific/medical dictionaries, not in abridged general-purpose ones.
It is pronounced /ˈtæneɪt/ (TAN-ayt), with stress on the first syllable, in both British and American English.
