Feminine nouns and adjectives ending in -e remain unchanged in the plural, keeping a form closer to the original Latin declension compared to the Italian equivalents. Thus unna ciave > doe ciave < duae claves “two keys” and unna noxe > træ noxe < tres nuces “three nuts”. Plural forms in -i, such as ciavi and noxi, are Italianisms widely spread especially in urban areas. Exceptions are feminines in -eise, whose plural form is now -eixi as in the masculine: unna zeneise > dötræ zeneixi “some Genoese women”.

This term may also occur with epenthesis (i.e. final addition) of the vowel -e. In Genoese, this phenomenon mostly affects monosyllables (such as mi [ˈmi] → mie [ˈmiːe] “I”, ti [ˈti] → tie [ˈtiːe] “you”, chì [ˈki] → chie [ˈkiːe] “here”, lì [ˈli] → lie [ˈliːe] “there”, scì [ˈʃi] → scie [ˈʃiːe] “yes”, no [ˈnu] → noe [ˈnuːe] “no”) and some bisyllables (ascì [aˈʃi] → ascie [aˈʃiːe] “also”; coscì [kuˈʃi] → coscie [kuˈʃiːe] “so”). It occurs especially when the word is at the end of the phonetic chain (thus, generally, at the end of a sentence) and serves essentially emphatic purposes. It is therefore a phenomenon typical of spoken language, and generally does not occur in written texts (unless, of course, they aim to imitate speech). Its use with nouns in -on [ˈuŋ] (staçion [staˈsjuŋ] → staçioñe [staˈsjuŋˑe] “station”) and with participles in -ou (cantou [kaŋˈtɔw] → cantoue [kaŋˈtɔwˑe] “sung”) is decidedly rare, and mostly restricted to certain areas.
