I've come across the following passage from Mina Murray's diary (from Dracula ). Mina is worried that her finance hasn't written to her for quite a long time.
No news from Jonathan. I am getting quite uneasy about him, though why I should I do not kno; but I do wish that he would write, if it were only a single line.
What will be the difference between would write and wrote in this case? I, personally, think that original sentence is entirely about the present. She wants him to to drop a few lines, and she still hopes that he'll do this. And with "wrote" it would mean sort of she wants him to have written to her. Somewhat she wants not to worry right now, but it's impossible because she got nothing from him, not a line. I've just shared my thoughts, but I'm not so sure about them. Possibly, someone can make it clear for me.
Many thanks!
