Instead of using "gypsy," it's much more respectful and accurate to use the self-identified terms of the various groups who have historically been referred to as "gypsies." These include:
* Roma (also called Romany or Rom): This is the largest and most widespread group.
* Travellers (also called Irish Travellers): This group is found primarily in Ireland and the UK.
* Romanichal: This group is found primarily in England and Wales.
* Other groups: There are many other smaller groups with their own distinct names and identities.
Therefore, there is no single collective noun for "gypsies" as it is not a culturally or historically accurate term.
It's crucial to be respectful of the diverse cultures and identities within these communities and use their self-identified names.
