Category:Nouns with unknown or uncertain plurals by language

Categories with nouns with unknown or uncertain plurals.

Terms are usually added to this category by specifying ? as the plural. As much is possible, a plural should be added or, if the noun is uncountable, indicated appropriately (usually using - in place of the plural). Some languages support the value ! to indicate that a plural cannot be attested but the noun is theoretically countable.

This is an umbrella category. It contains no dictionary entries, but only other, language-specific categories, which in turn contain relevant terms in a given language.
