What is the correct latin plural of the word "condominium"?

Question

Please help settle a friendly argument :)

Answer 1

Condominia would be the Latin plural.

The root noun is 'dominium', which is a second declension neuter noun meaning 'ownership.' The 'con' is a prefix meaning 'together', so it is something with 'ownership together'.

Plurals of 2nd declension neuter nouns are formed by dropping the '-um' and adding '-a', so the plural of dominium is dominia, and plural of condominium is condominia.

The 's' plural condominiums is based on English rules for plurals.
