Learn Turkish: Sen lütfen çok sebze ye. - You, please eat a lot of vegetables.

Turkish generally follows a Subject-Object-Verb word order. The subject Sen comes first, the object çok sebze is in the middle, and the action verb ye must go at the very end. This is a big difference from English, which puts the verb in the middle!

Why is it sebze instead of the plural sebzeler if the English translation says "a lot of vegetables"?

In Turkish, whenever you use a word that shows quantity or a number, like çok, you must leave the noun in its singular form. You never add the plural endings -ler or -lar after words like çok or specific numbers.

Why is the verb just ye without any endings?

Ye is the root of the verb yemek (to eat). When you are giving a command or a strong request to one person informally, you simply use the plain verb root with no extra endings.

Could I put lütfen at the very beginning of the sentence?

Yes, you can. Words like lütfen are quite flexible in Turkish. You could easily say Lütfen sen çok sebze ye. Putting it after Sen is just a style choice that slightly emphasizes the person you are talking to.
