Dear all,

as the concept of love has driven the mind of humankind to the most colorful and surprising associations of words in order to express it, I invite you to contribute to this topic with WORDS, SAYINGS, IDIOMS, etc you know, use or have heard related to this ineffable concept

Ateşle barut yanyana durmaz.
Fire and gunpowder cannot be at the same place. (Anything can happen.)

aşk çekmek - to suffer the paings of love
sevda çekmek- to be passionately in love, to suffer the pangs of passionate love
[-a] sevdayı sarmak - to fall passionately in love with
[a] sevdalanmak- to fall passionately in love with
sevdalı- person who is passionately in love
sevdiceğim- my darling, my beloved

gözümün nuru- light of my life, my beloved


gönül ferman dinlemez- the heart will always have its own way
gönlünü pazara çıkarmak- to fall in love with an unworthy person

Well, kind of kids saying but,

Aşk bir sudur, iç iç kudur.
Love is a water, you'll get crazier as you drink more.

Aşk bir vişne, ye ye kişne.
Love is a cherry, that makes you happy.
or Love is a cherry, you'll sing/say more as you eat more

All's fair in love and war
aşkta ve savaşta her şey mubahtır

It is better to have loved and lost than never to have loved at all
Hiç sevmemiş olmaktansa, sevip de kaybetmiş olmak yeğdir

Love is blind
Aşkın gözü kördür

Love me love my dog
gülünü seven dikenine katlanır

These are not all exact translations. They more like English phrases accompanied by their Turkish equivalents I found in an idiom dictionary ... especially the last one

I have found another two:

"Çok sevilirse çok "ah" edilir".
"Aşkın var ise dağlara düş".
