What does "birinin nazını çekmek" mean?

pander to one's whim?

We don't really use the verb "pander to", except in the case of a politician or an advertiser pandering to the whims of the people. It has a negative connotation. Does the Turkish phrase have this connotation too?

Let me put it this way, "naz" is a behaviour exhibited by generally girls in order to make boys begged by acting unwillingly. It hasn't a negative connotation as long as it's not taken to extremes. There is an idiom expressing this idea; "Fazla naz aşık usandırır".

OK; now I'm really confused - that sounds like flirting to me, or in old-fashioned English coquettishness. Why did you translate that as "whim"?

So the one in love measures how much the beloved is firting with him???

[NOTE: Flirting in English is VERY different from flört etmek in Turkish, unless the meaning has changed since I lived in Turkey - in English it is exactly what you described in your last post above.]

OK then.

The one in love measures how much the beloved is firting with him.

Is it correct now? I've made a few changes - I used "coquettishness" because if it was written by Rumi it can be a bit old fashioned.

Like I said, I'm not sure what the "çekmek" exactly means. Most probably, it should be "naza çekmek"?

Yeah, I think "naza çekmek" is more meaningful than "acı çekmek".

I think the last sentence should be “What is the beloved to do but play hard to get?"

I changed it again. It's still not "play hard to get" but it's a little closer, I think. What do you think?

Ellerine sağlık, güzel bir çeviri oldu.

Sağol - yine beraber çözdük.

naz çekmek ...> to accept coyness
What should the beloved one do instead of accepting coyness ?

But isn't it the beloved who is being coy here?

Yes s/h is.

I suppose Lein 3 is " Sevilenİ çekmesinde..." or "Seven çekmesinde...."
and
What should the lover one do instead of accepting (his/her)coyness ?

Sevilen (naza) çekmesinde neylesin? (kendisini naza çekmek)

What you are saying is "seven, sevdiğinin nazını çekmesin de neylesin?". The subject is not "the lover".

Yes I know them but I thougt "the lover" is better.

Siz karar verdikten sonra düzeltirim gerekirse.

I beg to differ.
