Number vocabulary and Ser

Question

Hola! In telling time "Es la Una" is one o'clock. My question is is there any thing wrong with saying "Es el Un" or "Es el Uno" since Una, Uno and Un mean the same thing and in number vocabulary to say the "one" its translated as "Uno"

Ps: I'm a beginner so I don't know if it is addressed in another lesson. My native language is English .

gracias

Answer 1

It has to be “es la una” because implicit in that is that the “una” is referring to the noun “la hora”. Which is a feminine noun.

“un” would need to come before a masculine noun.

“uno” would refer to a masculine noun that is dropped.

And “una” can either come before a feminine noun or refer to a feminine noun that is dropped.

In this case the una is referring to a feminine noun that is dropped:

Es la una (hora) de la tarde.
