النَّعْتُ تَابِعٌ يَدُلُّ عَلَى مَعْنًى فِي مَتْبُوعِهِ، نَحْوُ: «جَاءَنِي رَجُلٌ عَالِمٌ»، أَوْ فِي مُتَعَلَّقِ مَتْبُوعِهِ، نَحْوُ: «جَاءَنِي رَجُلٌ عَالِمٌ أَبُوهُ»، وَيُسَمَّى صِفَةً أَيْضًا.
Translation: Naʿt is a follower indicating a quality either in the noun it describes, as in “a learned man came to me,” or in something related to that noun, as in “a man whose father is learned came to me.” Naʿt is also called ṣifah.
In the first example the man himself is learned. In the second it is his father. This contrast generates the two main naʿt types.
