The vast majority of English nouns follow the regular pattern. Thus, new nouns that enter the
language usually take the regular plural. Irregular patterns are not extended to new nouns
usually (vax vaxen). The strong or irregular nouns are relatively stable and show little speaker
variation. There is some variation regarding nouns such as scarf, dwarf. Some frequently-occurring
foreign formations have been nativised in Modern English, while others remain confined to particular
registers.
Irregular plurals occur in compounds, while regular plurals don't:
oxen cart / *dogs cart
lice-infested / *fleas-infested
teeth cleaner / *hands cleaner
clothes basket
savings bank
