Learn Arabic (Modern Standard): نسيت البنت الصغيرة الدمية في الحديقة. - The little girl forgot the doll in the park.

Even though نسيت (she forgot) normally ends with a silent consonant marker (a sukun), you add a short i sound (kasra) when reading it out loud: nasiyati-l-bint. This prevents two unvoweled consonants from clashing when connecting the verb to the l sound in البنت.

Why does the verb نسيت come before the subject البنت?

In Modern Standard Arabic, the default sentence structure is Verb-Subject-Object (VSO). Instead of saying 'the little girl forgot' like in English, you say 'forgot the little girl the doll.' While you could use Subject-Verb-Object and say البنت الصغيرة نسيت, starting with the verb is the most natural way to report an action in MSA.

Why does the adjective الصغيرة have ال attached to it?

In Arabic, adjectives must match the noun they describe in definiteness. Because البنت (the girl) has the definite article ال (al-), the adjective الصغيرة (little) must also have it. If you dropped the ال and wrote البنت صغيرة, it would change the meaning to a complete sentence: 'The girl is little.'

The dictionary form of the verb is نسي (nasiya). Why does its final letter disappear in نسيت?
