[tag resources diglossia07005]چشما [/tag]češmā from [tag resources diglossia07006]چشم ها[/tag]čašm hā

[tag resources diglossia07007]دسا[/tag]dassā from [tag resources diglossia07008]دست ها[/tag]dast hā
‘hands, arms’

[tag resources diglossia07009]میزا[/tag]mizā from [tag resources diglossia07010]میزها[/tag]miz hā
