In one line
The verb-like particles — إِنَّ and its five sisters, which put the ism after them into nasab and keep the khabar in rafa.
Classical rule
وَأَمَّا إِنَّ وَأَخَوَاتُهَا فَإِنَّهَا تَنْصِبُ الِاسْمَ وَتَرْفَعُ الْخَبَرَ، وَهِيَ: إِنَّ، وَأَنَّ، وَلَكِنَّ، وَكَأَنَّ، وَلَيْتَ، وَلَعَلَّ.
“As for inna and its sisters, they put the noun into nasab and keep the predicate in rafa; they are: inna (indeed), anna (that), lakinna (but), ka'anna (as if), layta (if only), la'alla (perhaps).”
Key words in the Arabic
لَيْتَif only — wishing
لَعَلَّperhaps, in hope
كَأَنَّas if — likening
Understand it

Six particles that behave like verbs: doubled endings, verb-like meanings (assert, wish, hope), and a verb's power to govern — hence the classical name “resembling the verb”. Each recolours the whole sentence: إِنَّ insists, لَيْتَ longs, لَعَلَّ hopes. Spot one, and you know the next noun is in nasab before you read it. إِنَّ alone appears 1,682 times in the Quran; the family together, over 2,200.

The six, in the order they are taught
#Meaning
1إِنَّinnaemphasis — it confirms the khabar of the mubtada' and removes doubt about it
2أَنَّannathe same emphasis, but it must follow an expression its clause depends on, and it also forms a masdar
3كَأَنَّka-annacomparison or resemblance
4لَيْتَlaytaa wish, usually for what cannot be had
5لَكِنَّlākinnacorrection — it removes a misunderstanding created by what came just before
6لَعَلَّla'allahope for something liked, or fear of something disliked

All six work the same way: the ism goes into nasab and the khabar stays in rafa — the mirror image of كَانَ. They are called resembling the verb because they are built like verbs, three or four letters with a fatha on the last, and they govern like verbs. On an إِنَّ sentence you will often meet a لَ of emphasis sitting not at the front but on the khabar. That is the lam al-muzahlaqa, and it is explained on the page for اللَّام.

How to spot it
Recognition test
A doubled-nun particle (ـنَّ) opening a nominal sentence, first noun in nasab — one of the six.
In the Qur'an
يَكَادُ ٱلْبَرْقُ يَخْطَفُ أَبْصَٰرَهُمْ ۖ كُلَّمَآ أَضَآءَ لَهُم مَّشَوْا۟ فِيهِ وَإِذَآ أَظْلَمَ عَلَيْهِمْ قَامُوا۟ ۚ وَلَوْ شَآءَ ٱللَّهُ لَذَهَبَ بِسَمْعِهِمْ وَأَبْصَٰرِهِمْ ۚ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
Al-Baqarah 2:20 — “The lightning all but snatches away their sight; every time the light (Helps) them, they walk therein, and when the darkness grows on them, they stand still. And if Allah willed, He could take away their faculty of hearing and seeing; for Allah hath power over all things.”
اللَّهَ is the ism of inna (nasab); the khabar قَدِيرٌ keeps rafa, with the jarr phrase عَلَىٰ كُلِّ شَيْءٍ between them.

Common questions

What is the difference between إِنَّ and أَنَّ?

إِنَّ opens a statement (“indeed…”); أَنَّ embeds one inside another sentence (“…that…”). Grammatically they behave identically — ism in nasab, khabar in rafa.

Does لَعَلَّ always mean “perhaps”?

In the Quran لَعَلَّ frequently expresses purpose or hope — لَعَلَّكُمْ تَتَّقُونَ is closer to “so that you may attain taqwa” than to a doubtful “maybe”. Context decides.
