-ii

From rebracketing of plural forms like radii (plural of radius), borrowed from Latin. Latin forms the nominative plural of second-declension nouns by replacing -us with -ī, which results in plural forms that end in -iī for nouns with singulars ending in -ius. Some English speakers occasionally extend -ii to form nonstandard plural forms of English nouns that end simply with the letters -us or with other letter sequences with a similar pronunciation (such as -is /ɪs/).

• IPA^(key): (variously) /aɪ/, /i.aɪ/, /iː/

-ii

1. Misspelling of -i.
2. Used to form nonstandard, uncommon, often humorous alternative plural forms of nouns that end in -us, -is or a similar sound.

   Examples:

   ‎Elvis + ‎-ii → ‎Elvii

   ‎penis + ‎-ii → ‎penii

   ‎virus + ‎-ii → ‎virii

   ‎walrus + ‎-ii → ‎walrii

   ‎fetus + ‎-ii → ‎fetii

   ‎stewardess + ‎-ii → ‎stewardii

   ‎Airbus + ‎-ii → ‎Airbii

• All such forms are nonstandard, and therefore may be proscribed.
• For certain forms, such as cactii, a standard spelling with -i (cacti) exists; in this case, the -ii spelling may be simply a misspelling of the -i form.
• Other innovative plurals in -ii, such as stewardii, bear no resemblance to any standard plural form of the word; these may be used as intentionally nonstandard forms, often for the sake of humor. Compare the (often humorous) intentional use of nonstandard plural forms in -en.

From Latin -īvī (via -īī).^[1] Example: Italian finii, from Latin finivi.
