"A similar situation occurs in Oceanic languages. I remember reading that
Maori has a verbal flexion (past participle?) in -Cia, where C is the
dropped final consonant. When Maori speakers can't remember the final
consonant, they tend to assume /k/, leading to a slight tendency to make the
suffix -kia. Does anything similar happen in French?" Richard WORDINGHAM,

A by-default final? Sounds interesting. All I can remember for the moment
are wrong liaisons, as in
_*Moi -s- aussi._ [mwa zo 'si] for _Moi aussi._ [mwa o 'si] "Me, too."
