[Leica] Wow, the last word on bokeh, from Zeiss

[mark at rabinergroup.com (Mark Rabiner)]

The Nikonians:

Japanese term, pronounced BO-KEH in English, used to describe the out of
focus quality of a lens. Noun derived from the active verb "bokasu" which
means to befog, to gradate, to render opaque, to smudge or render out of
focus. It is usually the out of focus portions of the picture which
distinguish the "look and feel" or "signature" of different types of lenses.
The ideal boke for portraiture is a soft edged rounded blur with the
brighter part towards the center of the blur disk.
Classic boke is that of legendary lenses like the 105mm f/2.5 and 85mm f/1.4
Nikkor.
