Learn Turkish: Tebrikler! Çok güzel bir plan. - Congratulations! A very nice plan.

The base word is tebrik (congratulation). Just like in English, Turkish uses the plural form for standard wishes and greetings. You will see this same pattern in common phrases like teşekkürler (thanks) and iyi geceler (good nights).

Why is bir (a/an) placed after the adjective güzel?

In English, we say 'a very nice plan.' But in Turkish, the indefinite article bir almost always goes between the adjective and the noun. So the required structure is Adjective + bir + Noun. That is why it is written as çok güzel bir plan (literally 'very nice a plan').

Where is the verb in Çok güzel bir plan?

There isn't one! In Turkish, you can form a simple descriptive sentence without a verb like 'is' or 'are'. The phrase Çok güzel bir plan translates directly to 'A very nice plan,' but it also acts as a complete sentence meaning 'It is a very nice plan.' The 'it is' is simply understood from the context.
