Definition - The phenomenon where an adjective opposes or contradicts the noun it is modifying,m e.g. square circle and frozen fire. The result is an oxymoron.

Etymology -
The term derives from the Greek síderos, iron, and xylon, wood.

Oxford English Dictionary -
There is no OED citation for the term in this sense.


1. Two words for oxymoron. One surely must be extra. Can we save it for when we run short?
[ODLTguy: Nice try — but they aren't synonyms. The oxymoron is the thing, sideroxylon is the phenomenon that creates the thing.]
