Only this: だけ

Put だけ immediately after what you are limiting: コーヒー だけ means “only coffee,” and 私わたし だけ means “only me.” English usually puts “only” before the thing; Japanese attaches だけ after it.

The position of だけ tells you what is restricted. 水みず だけ 飲のみます means “I drink only water.” けんさん だけ 学生がくせい です means “Only Ken is a student.” Read だけ together with the words just before it.
