Circle is دَائِرَة (daira), square is مُرَبَّع (murabba), triangle is مُثَلَّث (muthallath), and rectangle is مُسْتَطِيل (mustatil). To describe an object, use a suitable adjective: a round clock is سَاعَة دَائِرِيَّة. A shape name and a shape adjective are not always identical.
01Learn the three starting shapes
daira
A round flat shape.
murabba
Four equal sides and four right angles.
muthallath
Three sides.
Use the outline to check the label. A triangle remains a triangle when rotated; orientation does not change its Arabic name.
02Recognise a rectangle
Modern Standard Arabic
هَذَا مُسْتَطِيلٌ
hadha mustatil
This is a rectangle.
A rectangle has four right angles. A square is a special rectangle with four equal sides, although beginner vocabulary exercises often show the longer rectangle separately. Mustatil names the shape and can also describe a masculine noun as rectangular.
03Change circle into round
daira
The shape itself.
saa dairiya
An object described by its shape.
Do not simply put the noun daira after every object. Dairi is the masculine adjective; dairiya is the feminine adjective. Arabic adjectives shows the wider pattern of describing a noun.
04Match the description to the object
Modern Standard Arabic
الْبِطَاقَةُ مُسْتَطِيلَةٌ
albitaqatu mustatila
The card is rectangular.
Bitaqa, card, is feminine, so mustatila has a feminine ending. With a masculine object, say الْبَابُ مُسْتَطِيلٌ (albabu mustatil), “The door is rectangular.” The English description stays the same while the Arabic ending changes.
05Separate a square from a cube
murabba
Square.
mukaab
Cube.
A cube has square faces but is not just a square. Similarly, daira is a circle while kura can mean a sphere or ball. Use the physical object or drawing to decide which word communicates the shape you mean.
06Add colour without losing the shape
Modern Standard Arabic
هَذِهِ دَائِرَةٌ زَرْقَاءُ
hadhihi dairatun zarqa
This is a blue circle.
Daira is feminine, so the feminine colour form zarqa fits. Keep the shape and the colour as separate pieces of information. The colour guide supplies more pairs; this lesson focuses on shape vocabulary.
07Describe something on your desk
Choose a card, a box, or a clock. Ask two questions: What is the object? What shape describes it? A round clock uses an adjective, while pointing at a drawn circle uses the shape noun.
Modern Standard Arabic
هَذَا صُنْدُوقٌ مُرَبَّعٌ
hadha sanduqun murabba
This is a square box.
In everyday description this refers to the box’s square form; the precise solid may need a different geometric term. Use adjective agreement to check the ending.
What to remember
- Daira, murabba, muthallath and mustatil name the four starting shapes.
- Use dairi or dairiya for round, according to the noun.
- A square is a flat shape; a cube is a solid with square faces.
