ÇÝÇEK SULANDIÐI KADAR GÜZELDÝR;KUÞLAR ÖTEBÝLDÝÐÝ KADAR SEVÝMLÝ;BEBEK AÐLADIÐI KADAR BEBEKTÝR VE HERÞEYÝ ÖGRENDÝÐÝN KADAR BÝLÝRSÝN

Thanks for your help.

 Sen verdiðin kadar alýrsýn : You take as much as you give

I think this should be

you get as much as you give (or receive as much as you  give)

My attempt:

ÇÝÇEK SULANDIÐI KADAR GÜZELDÝR;

It is as beautiful as a watered flower

KUÞLAR ÖTEBÝLDÝÐÝ KADAR SEVÝMLÝ;

With as much of my love as birds can sing

BEBEK AÐLADIÐI KADAR BEBEKTÝR

It is a baby as much as a baby cries

VE HERÞEYÝ ÖGRENDÝÐÝN KADAR BÝLÝRSÝN

and will you know as much as everything that you learn. 

would it be grammatically correct if I say :

Çiçek bakýldýðý kadar çiçektir : Flowers is as flower as it is  cared for.

Çiçek bakýldýðý kadar çiçektir : Flowers is as flower as it is  cared for.

No the grammar is wrong, and so is the sentence structure.

To start: It has to be

A flower is ....or   (The) flowers are....

I think çiçektir translates to ´it is a flower´

I think ´kadar iyidir´ can translate to ´as good as´

and ´kadar güzeldir´ can translate to ´as beautiful as´

because iyi and güzel are adjectives (sýfat) in this case,

but, ´kadar çiçektir´ cannot be ´as flower as´ in English

it is like saying ´kadar arabadýr´ means ´as car as´

which doesn´t make sense in English.

Çiçek bakýldýðý kadar çiçektir

I think translates to: ´the flower will be as good as it is cared for´,

meaning ´that if you look after it, it will be a nice flower"

Thank you Henry. Your comments are much appreciated and helps a lot.

I would also like to add some comments. Your explanations applies for Turkish grammar too. Normally in Turkish also you can not say "kadar çiçektir" because çiçek is not a "sýfat".

but in this poem (I suppose it is quite a famous one) poet uses the words as he likes without obeying the grammar rules.

I´m happy if I was able to help. 

That is why songs and poems are sometimes very hard to translate to the intended meaning, and literal translations make no sense to learners.
