Conjunction · حرف عطفThe prefix وَ at the front of وَتَكْتُمُوا۟ is a conjunction — a small joining word meaning 'and' — linking what follows to what came before; the word it joins in must stand in the same grammatical case as its partner before the joint — the same role in the sentence, even when the two words write that case with different endings. L4 · R4

Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. تَكْتُمُ is an action unfolding now: 'and conceal', from the root كتم: to conceal, hide. L1 · R7

Present Tense Verb · فعل مضارعA present-tense verb is the verb shape that opens with one of the four present-tense prefixes أ ن ي ت; small helper words before it can bend its time and mood. تَكْتُمُ wears that present-tense shape, opening with exactly such a letter: 'and conceal', from the root كتم: to conceal, hide. L8 · R3

Jussive Mood · الفعل المجزومThe jussive is the trimmed-down mood of a present tense verb; for the 'you all' shape the marker is the dropping of the final نَ. تَكْتُمُوا۟ has lost exactly that نَ, wearing the same trimmed ending as the forbidden verb it is joined to: the 'do not' reaches it too. L10 · R5

The Five Verbs · الأفعال الخمسةThe Five Verbs are the five present-tense shapes whose ending closes with the letter ن — يَفْعَلَانِ, تَفْعَلَانِ, يَفْعَلُونَ, تَفْعَلُونَ, تَفْعَلِينَ. وَتَكْتُمُوا۟ is one of them, but here its closing ن has dropped away — and for these five shapes that dropped ن is itself the grammar-sign: it marks the jussive mood, the bent form a governing word before it forces on the verb. L10 · R10

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word for 'I / you / he' that cannot stand alone — it is glued onto the end of another word, and each form carries within it exactly who is meant. وا۟ · 'you all/your' is fastened to the tail of the verb here — وَتَكْتُمُوا۟ — naming the one who did the action. L3 · R6

Doer (Fa'il) · فاعلThe doer is the one performing the action, so it stands in the nominative — the doer's form, usually shown by a ḍammah ـُ, a small curl above the last letter. The ending وا۟ on تَكْتُمُوا۟ is that doer, 'you all'; on this attached pronoun the shape is fixed, so no ḍammah appears, but the role it fills is the nominative one. L9 · R4

Definite Article · أل التعريفThe definite article is the prefix ٱلْ at the front of a noun (a naming word); it means 'the' — one specific, known one. The letter after it is a 'moon' letter — a letter not made in the same part of the mouth as ل — so the ل of the prefix keeps its own sound, both written and heard, resting with the sukūn ـْ (a small circle written above the letter): ٱلْحَقَّ. L2 · R9

Noun · اسمA noun is a word that names a person, place, thing, or idea. حَقَّ names such a thing: 'the Truth', from the root حقق: to be true, truth, reality. L1 · R6

Masculine Noun · اسم مذكرArabic treats every noun — every naming word — as grammatically 'he' or 'she'. ٱلْحَقَّ carries no feminine marker — no ة at its end, no final ى, no اء — so it takes the default and is treated as 'he': a masculine noun. L2 · R3

Accusative · منصوبThe accusative is the ending a naming word takes when the action lands on it, shown by a fathah ـَ — a small slanted stroke above the last letter. ٱلْحَقَّ ends in that fathah ـَ, sitting on its doubled قَّ. L2 · R11

Direct Object · مفعول بهThe direct object is the thing the action lands on, standing in the accusative — the landed-on form, shown here by the fathah ـَ on the doubled قَّ. The truth is what the forbidden concealing would land on. L9 · R3

Circumstantial Particle · واو الحالThe circumstantial وَ means 'while', introducing a mini-sentence that describes the state things were in during the main action. Its marker is that a complete topic-plus-comment sentence follows — أَنتُمْ تَعْلَمُونَ 'you know' — rather than a joined item: they conceal WHILE knowing. L14 · R3

Detached Pronoun · ضمير منفصلA detached pronoun is a standalone word for 'I/you/he'. أَنتُمْ is the standalone word for 'you all' — one of the twelve detached forms. L3 · R2

Subject (Mubtada') · مبتدأThe subject is the naming word a statement opens by talking about — its topic — standing in the nominative, the topic form usually shown by a ḍammah ـُ, a small curl above the last letter. A pronoun can serve as this topic, and أَنتُمْ 'you all' opens the 'while' sentence — a pronoun keeps one fixed shape, so no ḍammah appears, but the role it fills is the nominative one; 'know' is what is said about you. L6 · R2

Circumstantial (Hāl) · الحالThe ḥāl describes the state someone is in while the action happens, and one of its forms is a whole mini-sentence opened by the 'while' وَ. The sentence beginning with أَنتُمْ — 'while you know' — describes the state the concealers are in: fully aware. L21 · R6

Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. تَعْلَمُ is an action unfolding now: '[you] know', from the root علم: to know, knowledge. L1 · R7

Predicate (Khabar) · خبرThe predicate is the part that tells you something about the topic, and it can be a complete verbal sentence. The topic was أَنتُمْ 'you all'; the verb-sentence تَعْلَمُونَ 'you know' is what is said about you — the inner sentence itself carries the information, with no separate 'is' needed. L6 · R4

Present Tense Verb · فعل مضارعA present-tense verb describes an action happening now or still to come, and it is recognized by its opening letter — one of the four present-tense prefixes أ ن ي ت. تَعْلَمُ opens with exactly such a letter: '[you] know', from the root علم: to know, knowledge. L8 · R3

The Five Verbs · الأفعال الخمسةThe Five Verbs are the five present-tense shapes whose ending closes with the letter ن — يَفْعَلَانِ, تَفْعَلَانِ, يَفْعَلُونَ, تَفْعَلُونَ, تَفْعَلِينَ. تَعْلَمُونَ is one of them: its ending ونَ keeps that closing ن, and for these five shapes the kept ن is itself the grammar-sign that the verb stands in its plain, ordinary mood. L10 · R10

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word for 'I / you / he' that cannot stand alone — it is glued onto the end of another word, and each form carries within it exactly who is meant. ونَ · 'you all/your' is fastened to the tail of the verb here — تَعْلَمُونَ — naming the one who did the action. L3 · R6

Doer (Fa'il) · فاعلThe doer is the one performing the action, so it stands in the nominative — the doer's form, usually shown by a ḍammah ـُ, a small curl above the last letter. The و in the ending ونَ of تَعْلَمُونَ is that doer, 'you all'; on this attached pronoun the shape is fixed, so no ḍammah appears, but the role it fills is the nominative one. L9 · R4
