My comment here seems to have disappeared… strange
It said that although really is often used in the sense of 'actually', it can also sometimes also be used as a generic intensifier, its meaning can be exactly the same as 'very' or 'very much'. 'Really' can actually sometimes be translated as çok as well as 'oldukça' or 'gerçekten'
I wasn't really interested = actually
This is really easy = very, çok
