Why do so many people speak 'to' topics rather than 'on' or 'about' them? Is this a recent phenomenon? [closed]

"I will speak to that later." It seems to be most common in lecture theatres. Surely the preposition 'to' can only accurately refer to the hearer in this context. The topic itself is not the recipient. One may speak 'about' a topic or 'on the subject of' something or even 'around' it. They may 'touch upon' it but not speak 'to' it. Unless they are 'referring' to it... Have I answered my own question? Can speak replace 'refer'? One may refer people to topics. Can one say, 'I will speak to you to that later?' Can one speak people to a subject? I don't think so.

I really think there are so many other options that 'to' should not be one. When someone says, 'I will speak to that', I feel that it makes the listener rather unnecessary.


The Oxford English Dictionary has references to such a sense of the phrasal verb to speak to going back as far as 1610. It is listed as sense 5.

  1. To treat of or deal with, to discuss or comment on, (a subject) in speech or writing.

I think it refers to the idiomatic usage of speak to:

To address some topic:

  • The mayor spoke to the issue of tax increases.

(The American Heritage® Dictionary of Phrasal Verbs)

also, speak to something:

[for something] to address, indicate, or signal something.

  • This event speaks to the need for good communication.

  • Your present state of employment speaks to your need for a better education.

(McGraw-Hill Dictionary of American Idioms and Phrasal Verbs)

Thus usage is not very recent, Ngram shows usage of "speak to that issue" at least from the '60s but the expression is older than that.
