"It is a fashionable but very expensive skirt."

Translation: Це модна, але дуже дорога спідниця.

[Michael27b]

Would "Це спідниця - модна але дуже дорогa" not be kinda correct?

[va-diim]

No, because спідниця is feminine and needs the feminine ця.

[Neil124366]

why is the "it is" translated as "це" and not "Ця" to go with all the other feminine descriptors?

[va-diim]

Because "it is" always translates as the neuter це. Ця means "this" when describing a feminine noun, like ця спідниця, "this skirt." When you say "it is" or "this is," the translation is це.
