質問: I have found them in a manga. It is a dialogue discussing to the third person going into a Pachinko shop. Here is the full sentence. > > ジョーがやった台【だい】はガラスがはずしてあっただと > > > What do the words やった台 and はずしてあった mean?
回答: * やった It's the past (or perfect) form of a verb やる. This word doesn't contain more meaning than "do" does, but compared with する, it slightly emphasizes that the action involves physical movement. According to your context, it'd mean "played" here. * 台【だい】 That's the way we casually call *machine* like in "slot machine". * はずしてあった You can refer here for this grammatical construction. One point is: the `V + てある` pattern always requires a transitive verb's active form in V's position, but V is not necessarily what the subject of the sentence has done.
