Re: Use of the term Aikido"ka"
An interesting question. If asked, I would say I practice Aikido. However, the term Aikidoka, like judoka, is in common use in our style and is accepted in conversation without question.
When everyone in a conversation agrees on the meaning of a word, that is what the word means. If it has evolved, been appropriated from another language, or just been made up recently, once it has an accepted use it has a new meaning. You can not get rid of a new definition by referring to historical uses and etymology.
