Learn Farsi: دیگه الکی گریه نکن. - Don't cry for no reason anymore.

دیگه is the conversational Tehrani pronunciation of دیگر (other/more). When paired with a negative verb like نکن (don't do) in this sentence, it translates to "anymore" or "no longer". Therefore, دیگه... نکن means "don't... anymore."

How does the word الکی translate to "for no reason"?

الکی is a very common and heavily used colloquial word. As an adjective, it means "fake" or "unreal". But when used to describe an action (as an adverb), it means doing something "for no good reason," "baselessly," or "just making a fuss." Here, it describes the crying as unjustified.

Does دیگه have to go at the beginning of the sentence?

Not necessarily, but it is very common in spoken Farsi to place دیگه at the beginning of a sentence for emphasis. You could also put it right before the verb (الکی دیگه گریه نکن), which also sounds natural. However, unlike English "anymore," you generally cannot put دیگه at the very end of the sentence.

As a quick refresher, how is the negative command گریه نکن formed?

To make a command negative in Farsi, you replace the positive command prefix بـ (be-) with the negative prefix نـ (na-). The positive command for کردن (to do) is بکن (bekon), so the negative "don't do!" is نکن (nakon). The first half of the compound verb, گریه (crying), simply stays in front of it.
