	abstract = {Since Jun Li{\textquoteright}s original definition, several other definitions of expanded
pairs and expanded degenerations have appeared in the literature. We explain
how these definitions are related and introduce several new variants and
perspectives. Among these are the twisted expansions used by Abramovich and
Fantechi as a basis for orbifold techniques in degeneation formulas.},
