Adverbs

The word پیش means 'ago' if used as an adverb of time (and therefore without اضافه):


 * سه روز پیش : Three days ago

The same is true with بعد which means 'later', 'after that', 'then' or 'afterwards' as an adverb: The adverb هیچ ('any', 'at all') is generally used in negative sentences :


 * .هوا هیچ خوب نبود : The weather was not good at all.

Similar are the compounds with هیچ in which هیچ always bears the stress:
 * .هیچکس در خانه نبود : Nobody was at home.


 * .او هیچوقت در خانه نیست : He is never at home.
