etc. Dos mil, etc. 2,000
Treinta 30 Cien[53] mil 100,000
Treinta y uno _or_ Treintiuno, 31 Cien mil y uno 100,001
etc. etc. Cien mil y diez 100,010
Un millon 1,000,000

[Footnote 50: When immediately preceding a noun, "uno" becomes "un"]

[Footnote 51: "Ciento" becomes "cien." ("Cien" is found instead of
"ciento," even standing alone.)]

[Footnote 52: The duplicate forms are common to all the tens.]

[Footnote 53: "Ciento" drops the _to_ also before "mil"; and of course
before "millon" (a noun).]

The conjunction "and" is always used between tens and units, as--

Veinte y una or veintiuna manzanas (21 apples).

But it is generally omitted between hundreds and tens, as--

Doscientas treinta peras (230 pears).

"Ciento" and "mil" are not preceded by "uno" except in 101,000, 201,000,
etc., to avoid ambiguity, as--

Doscientos mil soldados (200,000 soldiers).
Doscientas y un mil millas (201,000 miles).

"One million inhabitants" is translated by Un millon _de_ habitantes.
(_Note_.--The _de_ cannot be omitted.)

In the case of more than one million the word "millon" must be
plural--millones, as--

Cien millones de hombres (one hundred million men).

As will have been observed, besides "uno," "doscientos," "trescientos,"
etc., change the _os_ into =as= for the feminine.
