I agree with all of the above comments.
Just one thing I would add is this: if you are certain that you want to apply this year, just start doing some language work, preferably in an institutional setting, even if it is one class a week or something.
You are obviously not going to become fluent in a few months. But, you can mention it in your application, and it will signal to the adcomms that you are serious and have given scholarly work some thought.
Languages can make a big difference, particularly at higher-ranked places, and you can put yourself at a disadvantage if you apply with no second language or prospect of acquiring one. Just my two cents.
