Inspiration in Chinese / Japanese...

靈感 is the Chinese word closest to hitting the mark for the English word inspiration.

In a more extended context, I have even seen this translated as “brain wave.”

The first character means alert, departed soul, efficacious, quick, effective, or intelligent.
The second character means to feel, to move, to touch, or to affect.
The combined meaning of these two characters changes a bit, but I think it's nice to know the individual meanings to give you a better understanding of where a word comes from.

You could describe this word as “the thought that pops into your head just before you patent the greatest widget ever invented that everyone in the world will want.”
At least, that's the idea.

This term can also mean “intelligent thought” if you translate it directly from each character. If you are looking for inspiration or need to be inspired, this is the word for you.

When the first character was absorbed into Japanese from Chinese, an alternate form became the standard in Japan. The Kanji shown to the right is the form currently used in Japan. This is still considered an alternate form in China to this day. it’s readable by both Chinese and Japanese people but if your audience is Japanese, I recommend the Kanji shown to the right - just click on that Kanji to order that version.
