"This is a white bird."

Translation: यह एक सफ़ेद पक्षी है।

[Sam362597]

Is 'ek' vital in sentences such as this? I must've been conditioned to leave it out but I keep getting marked wrong for that.

[zeebo7]

As far as I know it should be fine to leave it out.

[tre_mojosa]

Any idea why it's telling me I have a typo for सफे़द ?
I'm typing the middle letter as [letter],[thing on top],[dot on bottom].

[eltsandwich]

The dot should be to the side. Like फ़े - for me I have to type the dot first then the e marker
