in arabic a popular slang way of speaking is to add certain suffixes to words ... like a built in nick name for aminah(my real name) is amoonah ... a built in nickname for the name amira ... amoora ... samira .. samoora ... amir ... amoor ... and so on.. and also to add a 'ati' at the end ... amoonati... habibati (habib means lover or sweetheart) ... so my grandmother used to call me amoonati alot cuz she said it sounded like a queens name haha:)
another popular extension is amoonti ...
my dad has always called me helwa ... which means candy or sweets or pretty
i have a HUGE sweet tooth and so he always called me helwa
so helwati is just an extension of helwa lool as well as is .. heloool ... HAHAHA
so now that u have my life story hahahahah
