Thanks masaegu san. How about this verb "打つ"?
電報を打つ (send a telegram)
I would like to know if it is possible for me to use "打つ" when I want to say "Send a cellphone message to my friend"?
I very much doubt that I can use it to say "send a present to friend" and "send a letter"?
And also, what exactly is telegram? Do people still use telegraph these days?
