What is fond regards

"Fond regards" implies that you know the person well, and like them very much. It is not appropriate for formal letters.

In England, we might say "she is very fond of horses"; we actually mean she adores horses!

When writing to people we know well, such as family, we often sign our letters "love from ....."

You could send "fond regards" to someone you know well, but not quite well enough to say "love from..".

Hope this helps

No it doesn't mean you want to fondle them!

It just means a rather more friendly version of kind regards. You would only use it with people you knew but not people you had an intimate sort of relationship with, so not best friends or family, more old school friend you haven't heard from for years but used to be close to, you have fond memories of them.

Couldn't one sign fond regards to a person you were intimate with but not anymore?
