قواعد الإملاء: الألف المقصورة والممدودة

TL;DR

You'll learn when to write the letter "ألف" as a straight line (ا) called "ألف ممدودة" and when to write it as a small "ي" without dots (ى) called "ألف مقصورة". It mostly depends on the origin of the "ألف" in its root form, especially in three-letter words. This distinction is crucial for correct Arabic spelling.

1. The Mental Model

Think of the "ألف" as having two costumes: a tall, straight one (ا) and a bent-over one (ى). The costume it wears depends on what it used to be before it became an "ألف" in the past.

2. The Core Material

Arabic words often have a three-letter root. The type of "ألف" you use depends on the original letter it replaced (either "واو" or "ياء") in that root.

الألف الممدودة (ا) - The Straight Alif

You'll use the ألف ممدودة (ا) when:

• The original letter of the "ألف" was a واو (و). You can usually tell this by looking at the present tense of verbs or the plural/dual of nouns.

  • Verbs: If the present tense of a three-letter verb ends in "و", then the past tense "ألف" will be mمدودة (ا).

    • دعا (He called) -> يدعو (He calls) - here, the "ألف" in "دعا" came from "و".
    • سما (He rose) -> يسمو (He rises) - the "ألف" in "سما" came from "و".

  • Nouns: If the dual or plural of a noun shows a "و", the singular's "ألف" will be ممدودة (ا).

    • عصا (Stick) -> عصوان (Two sticks) - the "ألف" in "عصا" came from "و".
    • خطا (Step) -> خطوات (Steps) - the "ألف" in "خطا" came from "و".

• The "ألف" is in a noun with three or more letters and is preceded by a "ياء (ي)".

  • دنيا (World)
  • قضايا (Issues)
  • زوايا (Angles)

• It's in certain specific proper nouns and foreign words:

  • أوروبا (Europe)
  • أمريكا (America)
  • زكريا (Zachary)

الألف المقصورة (ى) - The Bent Alif

You'll use the ألف مقصورة (ى) when:

• The original letter of the "ألف" was a ياء (ي). Again, check the present tense of verbs or the dual/plural of nouns.

  • Verbs: If the present tense of a three-letter verb ends in "ي", then the past tense "ألف" will be مقصورة (ى).

    • رمى (He threw) -> يرمي (He throws) - the "ألف" in "رمى" came from "ي".
    • بنى (He built) -> يبني (He builds) - the "ألف" in "بنى" came from "ي".

  • Nouns: If the dual or plural of a noun shows a "ي", the singular's "ألف" will be مقصورة (ى).

    • فتى (Young man) -> فتيان (Two young men) - the "ألف" in "فتى" came from "ي".
    • قرى (Villages) -> قرية (Village, singular) - here, the "ألف" is present in the plural "قرى" and comes from "ي" in the singular.

• The "ألف" is the fourth letter or more in a word (verb or noun) and is not preceded by a "ياء (ي)".

  • مصطفى (Mustafa)
  • مستشفى (Hospital)
  • أعطى (He gave)

Here's a diagram to help visualize the decision process for three-letter words:

graph TD
    A["فعل أو اسم ثلاثي ينتهي بـ 'ألف'؟"] --> B{"كيف نعرف أصل الألف؟"};

    B -- "في الأفعال: المضارع" --> C{"مضارع الفعل ينتهي بـ 'و'؟"};
    B -- "في الأسماء: المثنى أو الجمع" --> D{"المثنى أو الجمع ينتهي بـ 'و'؟"};

    C -- "نعم" --> E["اكتب الألف ممدودة (ا)"];
    C -- "لا (ينتهي بـ 'ي')" --> F["اكتب الألف مقصورة (ى)"];

    D -- "نعم" --> E;
    D -- "لا (ينتهي بـ 'ي')" --> F;

    G["فعل أو اسم رباعي فأكثر ينتهي بـ 'ألف'؟"] --> H{"هل الألف مسبوقة بـ 'ي'؟"};
    H -- "نعم" --> E;
    H -- "لا" --> F;

3. Worked Example

Let's spell the word for "coffee shop" (مقهى).

1. Identify the word type: It's a noun.
2. Count the letters: م-ق-ه-ى, so it's a four-letter word.
3. Check the letter before the "ألف": The letter before the "ى" is "هـ".
4. Apply the rule: For a word with four or more letters, if the "ألف" is not preceded by a "ياء (ي)", it's written as "ألف مقصورة (ى)". Since "هـ" is not "ي", we use "ى".

Therefore, "coffee shop" is spelled مقهى.

Let's try another one: "He forgot" (نسى).

1. Identify the word type: It's a verb.
2. Count the letters: ن-س-ى, so it's a three-letter word.
3. Find the present tense: The present tense of "نسى" is "ينسى".
4. Check the ending of the present tense: "ينسى" ends in "ى" (which represents a "ي" sound).
5. Apply the rule: If the present tense of a three-letter verb ends in "ي", the past tense "ألف" is written as "ألف مقصورة (ى)".

Therefore, "He forgot" is spelled نسى.

4. Key Takeaways

• The "ألف" at the end of a word can be either straight (ا) or bent (ى).
• For three-letter words, its form depends on whether its origin was "و" (use ا) or "ي" (use ى).
• You find the origin of a three-letter "ألف" by checking the present tense of a verb or the dual/plural of a noun.
• For words with four or more letters, if the "ألف" is preceded by "ي", it's written as "ا" (e.g., دنيا).
• If the "ألف" in a four-letter-or-more word is not preceded by "ي", it's written as "ى" (e.g., مستشفى).
• Some foreign words or proper nouns follow specific conventions and might just need to be memorized.

5. Now Try It

For each of the following words, decide whether the "ألف" should be ممدودة (ا) or مقصورة (ى) and write the correct spelling. Explain your reasoning for each. (Hint: Think about the origin or length of the word.)

1. رجـ (رجـا / رجـى) - (Present tense: يرجو)
2. مشـ (مشـا / مشـى) - (Present tense: يمشي)
3. سلمـ (سلمـا / سلمـى) - (Proper noun, girl's name, more than 3 letters, not preceded by ي)
4. هدايـ (هدايـا / هدايـى) - (Plural noun, preceded by ي)

Success looks like correctly identifying the "ألف" type for each word and clearly stating why you chose that form based on the rules.
