وَيَجُوزُ حَذْفُ الْفِعْلِ حَيْثُ كَانَتْ قَرِينَةٌ، نَحْوُ: «زَيْدٌ» فِي جَوَابِ مَنْ قَالَ: «مَنْ ضَرَبَ؟».
Translation: The verb may be omitted when there is a contextual clue, such as answering “زَيْدٌ” to the question “مَنْ ضَرَبَ؟”
Ḥadhf (ellipsis) means an element is not spoken but remains understood from context. Here the question supplies the missing verb.
