"He is wearing a hat."

Translation: هُوَّ لابِس قُبَّعة.

I think the huwa should not have a shadda

[Yashanna1]

does the "he" have to be present?

[AniOhevYayin]

The sentence is similar to Israeli Hebrew but also different: ללבוש is commonly used in the sense of "to wear" with items of clothes; however, in this case a different verb (לחבוש) is used with hats. הוא חובש כובע, "he wears a hat." However, see TJ_Q8's discussion of the verb here: https://forum.duolingo.com/comment/33142309

Do we need to write the ھو?
