What is it?

Something is 'thinner' when it has less width or thickness compared to something else. It means it takes up less space from side to side or front to back. We use 'thinner' to compare two or more things.

Simple Example

Quick Example

Imagine you have two rotis. One roti is rolled out very thin, like a papad. The other roti is thicker, like a paratha. The roti that is rolled out very flat and has less thickness is the 'thinner' one.

Worked Example

Step-by-Step

Let's compare the thickness of three pencils.
---Step 1: Take three pencils. Pencil A has a thickness of 0.7 cm. Pencil B has a thickness of 0.5 cm. Pencil C has a thickness of 0.9 cm.
---Step 2: We want to find the thinnest pencil. We look at the numbers for thickness.
---Step 3: Compare 0.7 cm, 0.5 cm, and 0.9 cm.
---Step 4: The smallest number among these is 0.5 cm.
---Step 5: Pencil B has a thickness of 0.5 cm.
---Answer: Therefore, Pencil B is the thinnest pencil.

Why It Matters

Understanding 'thinner' is important in many fields, from engineering to art. Architects use it to design walls and structures, while fashion designers use it to choose fabrics for clothes. Even doctors use it to understand the thickness of bones or skin in medical imaging.

Common Mistakes

MISTAKE: Confusing 'thinner' with 'smaller in length' or 'shorter'. | CORRECTION: 'Thinner' refers specifically to width or thickness, not length. A long wire can still be very thin.

MISTAKE: Saying something is 'thinner' without comparing it to anything. | CORRECTION: 'Thinner' is a comparative word. You must compare at least two things to say one is thinner than the other.

MISTAKE: Thinking 'thinner' always means 'better'. | CORRECTION: Whether thinner is better depends on the situation. A thinner mobile phone might be nice, but a thinner bridge support would be dangerous.
