How do you tell if a word in latin is plural?

Answer 1

neuter means neither of the two and it is not a noun, it is an adjective.

(different person FYI)

Neuter can be a noun, and there are 3 genders:

NEUTER

Answer 2

You first have to learn the complex and lengthy rules of Latin grammar, since Latin is a language strictly governed by rules.

Every noun is either feminine, masculine or neuter and its ending changes according to how it is being used grammatically in a sentence; there are five sets of possible endings (called declensions), each applicable to specific nouns. Within each declension there are 6 singular and 6 plural endings called nominative, vocative, accusative, genitive, dative and ablative. These give a total of 60 possible word endings (30 singular, 30 plural) which must all be learned by heart.

A noun is often described by one or more adjectives which must "agree" with it - if the noun is plural, feminine and genitive, then the adjective must also be plural, feminine and genitive. The verb, if any, will also be a plural form if the noun is a plural. Latin would never say "The man they are digging", any more than English would. The context will very often provide clues to the meaning of a noun, which is why it is always wrong to isolate a Latin word from its context.

Nobody said Latin was easy, but if the ancient Romans could do it, anybody can!
