'anacardic' originates from the New Latin 'Anacardium', referring to the cashew tree, combined with the suffix '-ic' indicating a relation or connection.

'Anacardium' was derived from the Greek 'ana' meaning 'up' and 'kardia' meaning 'heart', referring to the heart-shaped fruit of the cashew tree.

Initially, it referred specifically to the cashew tree, but over time it evolved to describe substances derived from or related to the cashew.
