Lesson

1. Light Noon in the Imperative

Light Noon adds emphasis to a command, but it does not enter all 14 imperative positions.

FormsFeature
8Light Noon can enter
6Light Noon is excluded
نْLight Noon itself

Main map: 8 eligible + 6 excluded = 14.

2. Why Are Six Forms Excluded?

Light Noon does not come after an Alif in this paradigm. Therefore exactly 6 positions are excluded.

CountExcluded group
4all dual positions
2both feminine plural positions

Result: 14 − 6 = 8 eligible positions.

3. Active Direct Commands: Three Eligible Haadhir Forms

Among the 6 direct active Haadhir commands, only 3 can take Light Noon.

FormPosition
اِفْعِلَنْsingular masculine Haadhir
اِفْعِلُنْplural masculine Haadhir
اِفْعِلِنْsingular feminine Haadhir

The dual and feminine-plural Haadhir positions are excluded.

4. Active Ghaa'ib and Mutakallim: Five More Forms

The remaining 5 active positions use the command-Laam at the beginning.

FormPosition
لِيَفْعِلَنْsingular masculine Ghaa'ib
لِيَفْعِلُنْplural masculine Ghaa'ib
لِتَفْعِلَنْsingular feminine Ghaa'ib
لِأَفْعِلَنْMutakallim singular
لِنَفْعِلَنْMutakallim plural

Active total: 3 Haadhir + 5 Ghaa'ib/Mutakallim = 8.

5. Passive Commands: The Same Eight Positions

The passive Light-Noon imperative uses the same 8 grammatical positions.

FormPosition
لِتُفْعَلَنْsingular masculine Haadhir
لِتُفْعَلُنْplural masculine Haadhir
لِتُفْعَلِنْsingular feminine Haadhir
لِيُفْعَلَنْsingular masculine Ghaa'ib

لِتُفْعَلَنْsingular feminine Ghaa'ib
لِأُفْعَلَنْMutakallim singular
لِنُفْعَلَنْMutakallim plural

The person/number positions remain the same; the passive vowel pattern distinguishes the voice.

6. Three Ending Clues

The Light-Noon command has three especially useful ending clues.

ExampleClue
اِفْعِلَنْFathah before Light Noon
اِفْعِلُنْDhammah before Light Noon in masculine plural
اِفْعِلِنْKasrah before Light Noon in singular feminine Haadhir

The final Light Noon itself remains silent in all three.

7. Heavy Noon and Light Noon Compared

In the positions where Light Noon is allowed, the same grammatical position can appear with either emphatic Noon.

اِفْعِلُنْاِفْعِلُنَّplural masculine Haadhir
اِفْعِلِنْاِفْعِلِنَّsingular feminine Haadhir

Main difference: Heavy Noon is doubled; Light Noon is a single silent Noon. Light Noon also excludes all dual and feminine-plural positions.

8. A Simple Reading Map

Use this map: 8 eligible positions only.
• Active: 3 direct Haadhir + 5 Ghaa'ib/Mutakallim with command-Laam.
• Passive: the same 8 positions, all with command-Laam.
• Excluded: all 4 dual + both 2 feminine plural positions.
