I am reading Titus Groan, an eccentric 20th century masterpiece by Mervyn Peake. It is full of words I do not know.
abactina: As far as I can determine, the side of a radiate animal (like a sea urchin) opposite from the mouth. I think he uses it to mean something that’s been swallowed, that’s gone.
daedal: As one would expect, complex and ingeniously designed.
equipoise: Again rather self-evident; equilibrium.
hanger: A copse of trees on a steep slope.
monody: An ode sung or spoken by one person.
raddle: To mark as if with red ocher (also spelled ruddle).
screak: Meaning obvious, but interesting that it’s in the dictionary; screech, creak, shriek.
spilth: The act of spilling, amount or substance spilled.
tares: Weedy plants of the vetch family, or, by extension, an unwelcome element.
wodge: Bulky mass or chunk.
