limn -- verb tr.:
1. To portray in words.
2. To draw or paint, especially in outline.
Via French, from Latin luminare (to illuminate), from lumen (light). Ultimately from the Indo-European root leuk- (light), which is also the source of words such as lunar, lunatic, light, lightning, lucid, illuminate, illustrate, translucent, lux, lynx, and lucubrate. Earliest documented use: 1440.
And I quote the above because the word reminded me of Jan Cox: it was a word he used to describe what he was doing on stage, thousands of nights, to enable others to see in the direction he could. A task he shouldered knowing it was inherently contradictory---using words to point beyond words.
Jan said once, that if you don't know the origins of a word you cannot use it correctly. His example that night was 'cakewalk.' If you can wad up lightning, lynx, lunatic and translucent, in one instant, you might also get a glimpse of what he was pointing to.
