  1. Stroke 1: The short horizontal line at the top.
  2. Stroke 2: The left vertical stroke of the top component.
  3. Stroke 3: The right vertical stroke of the top component.
  4. Stroke 4: The horizontal line connecting the top component.
  5. Stroke 5: The horizontal stroke of the bottom "big" (大) part.
  6. Stroke 6: The left sweeping stroke (払 - harai) of the bottom part.
  7. Stroke 7: The right sweeping stroke (払 - harai) of the bottom part.

Radical Analysis

The kanji is composed of two main parts:

  • Top part (土 + 𠂇): Represents a fire or a person standing over a fire.
  • Bottom part (大): The radical for "big."
  • Combined Meaning: The character depicts a person standing over a fire, which makes their skin turn red. It is a pictograph representing the color of fire or blood.

Mnemonic

Imagine a big (大) fire burning on the ground. It is so hot that the person standing near it turns bright red (赤) from the heat!
