If it helps, they actually named it after their desired CLI abbreviation:

> The command-line tool is called jj for now because it's easy to type and easy to replace (rare in English). The project is called "Jujutsu" because it matches "jj".

[gcarvalho]

And the martial art is jiu-jitsu, not jujutsu. Similar sounding but definitely not “named after”.

No it's not, but so far the Brazilians are still sticking with the incorrect ~1908 way of writing it.

Standard Japanese pronunciation for "jutsu" does not contain an i, and it's also judo not "jiu-do" that the old system would have called for.
