thanks Henry, But if it used with a positive verb , I think it is means (NOW) is it right or not ?

The word for ´now´ is şimdi.

Artık means ´from now on´.

artık marks a turning-point, the moment when something is going to be different than it was before.

from the dictionary I learnt that artik meant "from now on" and "left over too" but don´t get how it also means left over, it confuses me..

artik as noun means left over, it has a different intonation than artik as an adverb.

ar-tık, noun, stress on the second syllable

ar-tık, adverb, stress on the first syllable

the noun artik derives from "artı"(plus, add, what is too much)

The word ´now´ isn´t only bearing the meaning ´şimdi´ but you may also translate it as ´artık´ ,which is exemplified in the following:

Benz´s first car is now in a museum in Munich. 

The baby can walk by himself now.

Focusing on the latter one specially,we can clearly see that the translation is better when translated as ´Bebek artık kendi kendine yürüyebiliyor´
