There are loads of word in Japanese which end in 込む, like 吸い込む, 読み込む, 入り込む, 打ち込む, 売り込む, 送り込む, 押し込む. How does adding ー込む change the meaning? What is the meaning that links all these words?
What are the essential Japanese counter words? For example -dai for machines, -mai for papers and stuff like that. What else to expect/know? Thank you
