Learn Farsi: میخک یک گل زیبا و ارزان است. - The carnation is a beautiful and cheap flower.

In Farsi, when making a general statement about an entire class or species (like "the carnation" as a concept, rather than a specific flower you are pointing at), you simply use the bare singular noun. No definite marker or plural suffix is needed to convey this generic meaning.

Why do we use و (and) to connect زیبا (beautiful) and ارزان (cheap) instead of chaining them with an ezafe, like گل زیبای ارزان?

Both structures are grammatically correct, but they have a slightly different feel. Chaining them with an ezafe (گل زیبای ارزان) layers the adjectives, sounding a bit like "the cheap beautiful-flower." Using و keeps them as equal, parallel descriptions, which flows very naturally in this context.

I have seen the word میخک used in recipes. Does it have another meaning?

Yes! میخک also translates to "clove" (the spice). Farsi uses the same word for both the flower and the spice, likely because of their similar visual shapes and the clove-like scent of some carnations. Context will always make it clear which one is meant.

How would this sentence be pronounced in casual, everyday spoken Farsi?

In colloquial speech, یک often shortens to یه (ye). Additionally, the â sound in ارزان shifts to a u sound (becoming ارزون), and the verb blends into the end of the word as an attached (e). The whole sentence becomes: (Mikhak ye gol-e zibâ va arzune).
