Koan

[Slava]

I know you were expecting this one, so here it is:

a nonsensical or paradoxical question to a student for which an answer is demanded, the stress of meditation on the question often being illuminating.

Origin:
1945–50; < Japn kōan, earlier koũ-an < MChin, equiv. to Chin gōngàn public proposal

'expecting it' ?
Was it related to an article printed somewhere???
Interesting word, however.
