First of all, it is necessary to write the تَنْوِين above the هَمْزة, but do you also need an additional Alif (ا) after it?
Let’s have a look at similar examples to understand the problem:
|with Aleph||meaning, explanation||root||examp.|
|1||yes|| a piece; a portion|
If the word functions as a direct object (مَنْصُوب), it is written like this: جُزْءًاFor example: I want a piece.
The root literally means: to spend the winter. The ء belongs to the root. It was originally a و that was transformed to a ء
|in the evening||م–س–و||مَساءً|
The rules for writing the final Aleph
- If there is an Alif before the هَمْزة, you don’t write an Alif after the هَمْزة if the word is in the مَنْصُوب–case.
- If there is no Alif before the هَمْزة, like in the word جُزْء, you write an Alif after it. Why? The هَمْزة is part of the root!
