# Category:English nouns with unknown or uncertain plurals

This category contains entries that use `{{en-noun|?}}`, which indicates that the plural of the given entry is yet not known. As much as is possible, a plural should be added or, if the noun is uncountable `{{en-noun|?}}` should be converted to `{{en-noun|-}}`. If a plural cannot be attested but the noun is theoretically countable, use `{{en-noun|!}}`.
