Is this true, If I say "They’re having a dance." instead of "They’re dancing."?
Answer
"Having a dance" is not generally used in this sense. It is (rarely) used to mean "organising a dance party".
The Women’s Institute will be having their annual dance on the 1st of June, and are seeking gentlemen partners who are able to tango.
I saw a group of teenagers having a dance around a portable speaker in the school common room.
