resin
UK: ˈrɛzɪn | US: ˈrɛzən
n. a sticky substance secreted by some plants, often used in varnishes, adhesives, or medicinal products.
n. a synthetic polymer with similar properties to natural resin.
The word "resin" traces back to Latin resina, likely borrowed from Greek rhētinē, referring to the viscous sap of pine trees. The prefix re- (though not always active in meaning here) historically reinforces the idea of a substance that "flows back" or is repeatedly secreted. Over time, the term expanded to include both natural plant secretions and synthetic compounds with similar properties.
