Question 18

1

Answer 18

unus

Cardinal number.
Inflects like a normal 1st/2nd decl. adjective

unus, una, unum

Question 19

Does unus have a plural form?

Answer 19

Yes!

Although it may seem strange at first sight, ūnus does have a set of plural forms. These forms are used when the associated noun has a plural form, but an inherently singular meaning. For example, the Latin noun castra (“camp”) occurs only as a plural neuter form and takes plural endings, even though it identifies one object, hence: ūnōrum castrōrum (“of one camp”).

Question 20

Does unus decline when used in the compound numerals such as twenty one.

Answer 20

Yes!

When ūnus is used to form compound numerals, such as ūnus et vīgintī (“twenty-one”), the case and gender agree with the associated noun, although the singular is used: vīgintī et ūnam fēminās vīdī .

Question 21

Is ūnus mīlle in common usage?

Answer 21

No!

Unlike duo and trēs, the word ūnus is almost never used with mīlle (“thousand”) to indicate how many thousand.

Question 27

duos/duo, duas, duo

Answer 27

masc, fem, and neut of duo (two) in the accusative case.

Question 28

Do cardinal numbers decline in latin?

Answer 28

Most cardinal numbers are indeclinable - they behave like indeclinable adjectives.

The exceptions which do decline are unus, duo, tres, multiples of centum, although not 100 (ie centum) and mille.
