I am having difficulty understanding how you don´t pronounce the letter ğ. for example how would you pronounce "yoğurt"? An helpful tips?

the letter yumuşak ( ğ )soft g

yo urt

ağri  (aaaari ) - pain

ari  (ari)  - bee

for most of the time think of it like the K in the work knife it is silent

** If ğ is the last letter of a word, or it is followed by a consonant, extend the vowel sound before it. Dağ Ağla Oğlan

** All other times, when ğ has vowels on both sides, it is silent and simply serves to visually (when writing) separate the two vowels. Ağır Bağır

Not quite. ğ marks the border of syllables.

The other day I was listening to Neşet Ertaş and I am sure I heard him pronounce a voiced velar fricative [ɣ] in the place of ğ.

 for a beginner what I wrote should be helpful

ğ in conjunction with front vowels is heard like a weak y

for instance: öğle, değer, diğer, eğer, değil

but never in meğer

NB: according to Lewis Turkish Grammar

Thank you! I felt that at times it sounds like a y but other times it´s completely ignored. It´s so difficult to not over pronounce the y sound, but I guess i´ll learn over time

raise the back of your tounge towards the upper side of the back of your mouth but dont close it completely. and slightly press the front of your tounge downwards. any sound that comes with this makes ğ. it sounds as if it takes the sound of the vowel in front of it. like eğer - eer  dağ - daa etc. but actually its just a very soft throat sound like x in persian or r in dutch. but soft.

sometimes it can sound like y or ı as well.

That was actually very helpful, thank you!
