I was just going over the vocabulary and i came across some words that confused me a little.. i know that 'ama' means 'but' and then i read that on the vocabulary that 'fakat' also means 'but' so how do i know what word to use in sentances?
also
veya = or
ya da = or
again how do i know what word to use in simple sentances?

fakat, ama, lakin are synonym.

synonym - eş anlamlı

'lakin' is old fashioned. It is almost omited from the language.

'Fakat' and 'ama' are used. I always pick 'ama' and almost never use 'fakat'.
