Dating ad acronyms
An acronym is a word or name formed as an abbreviation from the initial components in a phrase or a word, usually individual letters (as in NATO or laser) and sometimes syllables (as in Benelux).
There are no universal standards of the multiple names for such abbreviations and of their orthographic styling.
Newspapers and magazines that take personal advertisements often provide a reply forwarding service; in this case, the text of the advert will include a unique box number and anyone wishing to reply to the advert sends or delivers their reply to the publisher's address in an envelope bearing that number.
The publisher forwards replies in bulk to the advertiser at a given interval, for example each week.
When it is time to write your own ad, the most important thing you should do is to be honest.
