I use to use "post lunch" to inform a person about fixing up the meeting time if it is in the afternoon office time. apart from that I have never used it in any of other conversation.
recently, In British council website I read the following sentence " You will also have a chance to interact with our expert teacher who will help you identify your English learning requirements, post this you can enrol for a course that suits your requirement."
In the above sentence post is used. If the same information, if I would have written, I would have used "After". since the above sentence is from British council, definitely they are right.
My question now is, Can I interchangeably use after and post? or is Post and after has got a different meaning and should be used appropriately? if so, How can I trigger myself choosing the right word?
Best Answer
After and post are often interchangeable. The latter tends to have a more formal tone. So I would tend to say "a post lunch meeting" but "an after lunch nap". Post can also more strongly imply an era -- "post World War II Germany" sounds much better than "after World War II Germany" or even the more grammatical "Germany after World War II".
In your example of "... identify your English learning requirements, post this ...", I agree with your gut feeling. After flows better than post, which to my ears sounds stuffy and overly formal.
As far as a general rule, after is more common. If you feel that you are identifying an era, choose post. Also, post would sometimes work better if you are striving for formality. (As your example shows, the formality can go too far.)
