Here are some of the terms that should be avoided:
* Gypsy
* Romany
* Traveller
Instead, it's important to use the respectful and accurate terms:
* Roma (singular: Rom) - This is the most common and preferred term for the people who identify as Roma, and is used by most Roma people themselves.
* Romany - This term is sometimes used, but it's important to be aware that it may be seen as outdated or potentially offensive by some Roma people.
It's also important to understand that the Roma are not a homogenous group and may identify with different sub-groups or have different cultural practices.
Ultimately, the best way to refer to the Roma people is to use the term they prefer and to be respectful of their culture and history.
