A Hundred and One Rules in Arabic Grammar!
- The Nominalizer إنَّ & her Sisters ( لعلَّ ، أنَّ ، کأنَّ ، لکنَّ ، لأنَّ ) ===============================================================================
The Nominalizer إنَّ & her Sisters ( لعلَّ ، أنَّ ، کأنَّ ، لکنَّ ، لأنَّ ) change the subject nominative case marker to the accusative but they leave the predicate in its nominative case. By the way, أنَّ / إنَّ are called "Nominalizers" because they introduce nominal sentences.
**إنَّ الأکلَ لذيذ ٌ.**
In fact, the food is delicious.
** قالتْ اُختي أنَّ الأکلَ لذيذ ٌ.**
My sister said that the food was delicious.
**لکنَّ الأکلَ لذيذ ٌ.**
... but the food was delicious.
إنَّ is only used in the initial position of a sentence, and following any form ofقالَ . Anywhere else you have to useأنَّ . Its meaning, therefore, changes from "indeed/in fact" to "that". Remember that all these particles should be followed by nouns or attached pronoun suffixes. Also notice that** إنَّ** and her sisters should be followed by the subject or its corresponding attached pronoun.
