There is/are

In the previous lesson you learned about prepositions (+ noun) as the second part of the nominal sentence. In that case the first part is definite (or a pronoun).

Now it may happen that the first part is indefinite and the second is a preposition+noun, in which case the order is reversed and the second part with the preposition+noun comes first. This is due to the fact that a sentence cannot start with an indefinite noun.

Let us take the examples given in the last lesson and modify them to make their first part indefinite.

There is
EnglishArabic
there is a child in the houseفي البيتِ طفلٌ
there is a book on the deskعلى المكتبِ كتابٌ
there is a ball under the chairتحتَ الكرسيِ كرةٌ
there is a bicycle in front
of the car
أمامَ السيارةِ دراجةٌ
there is a broom behind the doorخلفَ البابِ مكنسةٌ

The first part (now placed in the second position) retains its vowelling. It can also be dual or plural, e.g:

There are
EnglishArabic
there are two children in
the house
في البيت طفلانِ
there are some children in
the house
في البيت أَطفَالٌ
there are some engineers in
front of the building
أمام العِمارة مهندسونَ
