The compounds of uña “one” fem. maintain the feminine form whenever they have a pronominal role. For instance, when counting objects with feminine gender, such as playing cards, one will say uña, doe, træ, …, vinti, vintuña, etc.

The adjectival forms, however, are usually identical to the masculine. One will therefore say gh’ò vintun carte “I have twenty-one cards”; forms such as gh’ò vintuña carte are infrequent.

Ordinal numbers are declined like regular adjectives. Therefore:

• forms ending in ‹-o›: o primmo “the first” masc. sing., a primma fem. sing., i primmi masc. pl., e primme fem. pl.;
• forms ending in ‹-en›: o sezzen “the sixteenth” masc. sing., a sezzeña fem. sing., i sezzen masc. pl., e sezzeñe fem. pl..

For ordinals beyond the 9th there are two forms, those ending in -en and those ending in -eximo.

The forms ending in -en under the 20th (dexen “tenth”, unzen “eleventh”, etc.) are typical of Genoese. The ones ending in -eximo (deximo, unzeximo, etc.) are based on Latin, and are more and more frequent due to the influence of Italian, which has analogous forms. Nowadays, one can even hear cardinals completely modelled after Italian, such as undiceximo.

Ordinal forms beyond the 19th are not very common in spoken Genoese, especially those ending in -en, which – although they form the regular pattern – have long been obsolete. As can be seen in the following note, cardinal forms are often used in their place.

In place of the standard ordinal forms, especially for higher numerals, it is common to use the cardinal forms in certain contexts. One may therefore hear o giorno vinti da mæ vixita “the day twenty of my visit” instead of o vinteximo giorno “the twentieth day”; l’ediçion trenteçinque da regatta “the edition thirty-five of the regatta” instead of a trenteçinquexima ediçion da regatta “the thirty-fifth edition of the regatta”, etc.

The form citto  denotes:

• the hundredth part of any currency (un cafè o costa un euro e dexe citti “a coffee costs one euro and ten cents”);
• the centimeter, the hundredth part of the meter (un päfæro de doî metri pe trenta citti de diametro “an iron post that is two meters long by thirty centimeters of diameter”).

Collective numerals ending in -ña have regular plural forms in -ñe.

The forms çentanâ “a hundred (or so)” and miggiâ “a thousand (or so)” are masculine in the singular form, but feminine in the regular plural forms çentanæa  and miggiæa  respectively. The forms çentanæe and miggiæe can also be found.
