kadın - bayan

 kadın = woman

 bayan = lady, madam [ polite way ]

 Both mean woman. The second is a bit politer. Like the difference between woman and lady.

Some examples where kadın is used and bayan is not:

Male/Female is always Erkek/Kadın

Some example where Bayan is used and kadın is not:

Before someone´s name as a title e.g. Bayan Mary

Toilets: Bay/Bayan

In the formal introduction "ladies and gentlemen" - "baylar bayanlar"

Tunci´s too quick.

Yes, but not as good as you [ your explanation ] Mazzer !

 You´re too kind. Couldn´t think of another example where it is always kadın and never bayan, can you?

(I didn´t count aysekadın in the vegetable´s name!!)

No, no, both explanation was very useful.

The shorter is better for the visually learners and the long term memory, the longer is better for the learners who like to dig deep and slowly digest the info. Or so I made it all up. Not bad, eh?

Thank you!

For example ;

Bu hastane´de kadın doğum  bölümü var.   [ This is term used in hospitals, I always see it as kadın doğum ]

I know it might not make sense in english saying ;

In this hospital ,there is women birth department.

Another one would be ;

Kadın hastalıkları [ women diseases ] which is another medical term that i havent seen it used as " Bayan hastalıkları "
