Well, I don't know about the words that came before Aikido, but Aikido came from Aikijiujutsu. When...now I don't know the name of the founder of Aikido, but Hapkido too came from Aikijiujutsu.
Ultimately, the teacher of Choi Yong Sul and the founder of Aikido committed suicide and both took their knowledge and tweaked it to create new styles. Aikido and Hapkido were born. Very brief history lesson for you
