The reason Bokeh is spelled with an "h" at the end

[Grumpy Old Guy]

5. Perhaps I've been misinterpreting the term.

The word "bokeh" became popular in the late nineties when I was taking a hiatus from photography. I was still working, and busy raising two kids then, and didn't have much time for anything else.

I am familiar with the circular light effects produced by mirror lenses. I didn't think a specific shape of halos was necessary for good bokeh. I just interpreted the term as a pleasing out of focus background.

I have a friend who is relatively new to photography. He recently asked me for advice about a family portrait he shot. He ruined it by poor subject placement. He had the family placed evenly along a plane perpendicular to the lens, but he placed one little girl slightly in front of the group. He shot it wide open in an effort to get good bokeh. Unfortunately, the girl was soft. I explained what happened, but unfortunately there was no way to fix it.

These days I often apply my background blur in Photoshop and Adobe Camera Raw.
