Contraction in Turkish

In some words or phrases , two or more vowels are compressed and becomes one vowel when they are formed as one word. 

kahve  altı      ---->  became one word [kind of compressed]  ------>  kahvaltı [breakfast]

[before the coffee]

[lit. under the coffee] 

In daily verbal language people say it even shorter  as " kavaltı" [this way the first "a" is pronounced bit longer]

----------------------------------------------------------------------------------------------

pek   iyi    ------>   peki  [last two "i" become one "i"] ----> means " all right" , "okay", " well" ….
