Prepared to
From 'Vocabulary' part of The ABC Of Plain Words by Sir E Gowers (1951)

A foolish habit has grown up recently of saying someone is "prepared" to do something when what is meant is that he is doing or even has done it. When you say

"the Minister is prepared to consider your application if you will submit it in the prescribed form",

that makes sense. But when you say (as I have seen over and over again) something like this:

"The Minister is prepared to approve your application, and I enclose the necessary licence",

that makes no sense. The preparatory stage is clearly over. Here is an example of the absurdities into which a writer can be led by this silly trick:

I have to acknowledge your letter of the 16th June and in reply I am prepared to inform you that I am in communication with the solicitors concerned in this matter.
