"His friend Samia is wearing a skirt."

Translation: صَديقَتهُ سامْية لابِسة تَنّورة.

[tsuj1g1r1]

Again, your choice to introduce لابسة as MSA is misleading in my opinion. صديقته سامية ترتدي تنورة.

[OmarKhaled5509]

أو تلبس التنورة.
لابسة is MSA but not in this sentence.

[ThinkerXT]

The proper Arabic name is سَامِيَة with a kasrah and it is a noun in the language that has a meaning. It is the feminine of سَامِي , just check a dictionary to see how it should be spelled and so pronounced.

[Djibril487949]

So I know Duo isn't pronouncing declined endings any more, but just for the record, should the adjective be "لابسةٌ" in this case?

[Ahmad486285]

Instead of LAABESEH I used LAABES still marked correct? Confusing! Or both are correct
