Relating to or resembling a chestnut, particularly in color (reddish-brown) or characteristics.
From 'castanea' (Latin for chestnut) plus the adjective suffix '-ane' or '-ine,' used to describe chestnut-like qualities.
This word is mostly obsolete, but it's a beautiful example of how English once had specific adjectives for every color and material—we've simplified our language by dropping these descriptive words.
