"Draeger notes, You will see this spelled, by the way, like this - jujitsu, jiujitsu, and so on. This one, - jujutsu - is the correct one as far as the Romaji, the alphabetical writing (of the Japanese language)... This one - jujitsu - is a mistake, ..."
Cited by Davey, H.E. Unlocking the secrets of aiki-jujutsu.Indianapolis: MASTERS PRESS, 1997, p. 3, in which he cites Draeger, Donn F. Classical studies in bujutsu.New York: Weatherhill, 1973, p1.
For further discussion also consult George Arrington of Danzan Ryu at:
Jujutsu, Jujitsu, Jiu-Jitsu...Which is correct?
My own conversations with one of the leading authorities in Japanese martial arts and culture in the USA,
Dr. Steve Cunningham (7th Dan, Takagi Ryu Jujutsu), provide further support to Draeger's assertion.
I am also inclined to agree.
