‘Revert’ as meaning ‘get back to you’ - is this right?

[TraceyDeacy]

I am hearing ‘revert’ quite often as meaning ‘reply’ and am perplexed as to where it has come from.

I have never heard the word used in English before this year. Etymologically, I thought it might mean ‘turns back’.

No, it's not.

Thank you. It's definitely not American usage.

In my work they often use it to say " revert to type " so I've always taken it as going back to what it was before
