Is there a pleural form of adieu in english?

Answer 1

In English, "adieu" does not have a commonly used plural form, as it is borrowed from French and typically used as a singular farewell. However, if one were to refer to multiple farewells, one might informally say "aduies" or simply use "goodbyes" instead. Ultimately, the context in which "adieu" is used often dictates whether a plural form is necessary.
