Although hijab is not an English word, it is commonly used in English to describe the head scarf worn by many Moslem women.
I was pretty sure I had just heard Christiane Amanpour of CNN call the plural "hijub", and that made me go to look up the correct plural.
There seems to be a disagreement among different sources.
WordForum calls the plural hujub (singular hijab)
Wikionary says it is hijabs.
In a case like this, where the original language has a plural different from a usage in English, which should be used? [I am aware of the precedents set by Greek plurals, and I would like to side-step all that.]
