How would you say "It is a girl"?
"Ez egy lány."
translation lacks is
This is not a full sentence, merely a phrase.
ez a lány = "this girl"
For example, Ez a lány vár. = "This girl waits." (That's a full sentence with a capital letter at the beginning and a full stop at the end.)
I guess so.
Where is "is"? This is a girl
ez a lány does not mean "This is a girl." (full sentence, with verb, capital letter at beginning, "." at the end).
ez a lány means "this girl" (not a full sentence -- no verb, no capital letter at beginning, no punctuation at the end).
Why use fracions? Makes no sense.
